President's
Corner
Dennis Gertenbach
As I
write this, the
temperature is over 60,
even though it is still
January. The warm
weather makes me long
for the field trip
season, and I have
started planning where I
want to go rockhounding
this year. If you're
feeling the itch to plan
your outings, the
Flatirons Mineral Club
can provide some of the
best resources around
for planning your trips.
First, check the club
library.
Ray Gilbert, club
librarian, can provide
you a list of the
resources we have,
including books, maps,
and other information.
Next, talk to other club
members at the next
meeting. Many of our
members have a wealth of
information about where
to go and what to find.
Lastly, plan on
attending the club field
trips. Better, yet, lead
a field trip.
Paul Boni can help
you plan a club trip and
will provide the
necessary paperwork.
Leading a trip last year
was one of the most
enjoyable activities I
had with the club.
See you
at February's meeting.

Club
Meeting
Thursday,
February 10, 7:00 PM
West
Boulder Senior Center,
9th & Arapahoe
For our
February meeting, we
will be treated to some
special entertainment.
Club members Carol and
Mihail Codrescu will
come with other members
of their folk-dancing
group and will give us a
short show (on the
stage) of Romanian folk
dancing. In addition we
will have refreshments,
door prizes and our
usual short business
meeting, and will swap
stories from our
rockhounding trips, time
permitting.
Coming up
for future meetings, we
will have the renowned
Ed Raines in March, and
his topic will be "The
Geology, Mineralogy, and
Mining History of the
Aspen District." For the
April meeting, we will
have Waverly Persons of
the USGS talking about
earthquakes and the
effects of earthquakes.
Our annual silent
auction is tentatively
scheduled for the June
meeting.

Jr. Geologists Finish
the Rocks and Mineral
Badge
Dennis Gertenbach
In
January, the Jr.
Geologist completed the
requirements for the
Rocks and Minerals
badge. For the last
several months, they
have been studying about
rocks and minerals,
learning to identify
minerals, identifying
crystal shapes, and have
put together an
identification kit to
help with mineral
identification.
At the
next meeting on
Thursday, February 24,
we will begin working on
our second badge. The
meeting will start at 7
p.m. and is opened to
all club families.
Please contact
Dennis
Gertenbach for the
location.

Get Your Newsletter By
E-Mail!
Perhaps
some of you have just
gotten on-line over the
recent holiday season,
but you are still
receiving your
newsletter by surface
mail. Now is the time to
switch your subscription
to an e-mail
subscription. There are
several advantages to
getting the e-mail
edition, as opposed to
the print edition:
1. Color
pictures--the printed
version is in black and
white only. If you have
a color printer, you can
print your newsletter
and have the pictures in
color!
2.
Clickable URL's--for
example, check out this
nifty web site that has
a complete on-line
database of minerals and
mineralogy:
http://www.mindat.org.
If you get the print
version, you have to
type this address in
your web-browser's
address box. But with
the electronic version,
all you have to do is
click it!
3. More
up-to-date--last minute
changes, corrections, or
additions can be made to
the electronic version
after the print version
has already gone to
press.
4. Faster
delivery--you receive
the e-mail version as
soon as it is mailed out
(within seconds).
The print version takes
2 or 3 days to be
delivered after it is
mailed.
5. Saves
your club the postage
and printing costs.
To access
the electronic version
of the newsletter, you
will need to have the
Adobe Acrobat Reader
installed on your
computer. This is a free
download from the Adobe
website (version 7.0
just released!):
http://www.adobe.com/products/acrobat/readstep2.html.
You can
print the e-mail
newsletter
"back-to-back" on your
own printer, so it will
look just like the
printed version (except
the pictures will be in
color if you have a
color printer). See the
instructions that came
with your printer on how
to do this. Most
printers make it very
easy to do so, prompting
you through the process,
and showing how to
insert the pages back in
the printer to print the
odd pages after the even
pages are printed.
To change
your subscription, you
need to notify our
membership chairperson,
Trick Runions and
you need to send your
e-mail address to
Dennis
Gertenbach, who actually
sends out the e-mail
version of the
newsletter.

Sumatra Earthquake and
Tsunami A selection of
websites
provided
by Pete Modreski
Obviously
a great deal has
appeared in the news
media about this tragic
event, and most of you
have probably received
numerous emails giving
links to information
resources about it
through different
science education
listservers. I'll just
list here what I think
are several particularly
good sources of
information, some of
which may be new to you.
The USGS Website has, in
addition to maps and
data on the earthquake
and aftershocks, an
excellent set of "FAQ"s
about the earthquake and
tsunami—including such
things as comments on
the effect on the
earth's rotation and the
estimated amount of
seabed movement caused
by the quake. See the

Field Trip Chair and
Secretary Still Needed
By Paul Boni
We're
still looking to fill
two positions, field
trip chair and
secretary. Neither job
is difficult and both
are important to the
vitality of our club.
I've been the field trip
chair for two years,
program chair for two
years before that, and
feel it's time to let
someone else have a go
at it. Emily Epstein has
been our secretary for
several years but has
moved to Aurora. She has
continued as secretary,
commuting all that
distance, but honestly,
the commute is too much
for her.
Field
trips are one of the
main attractions,
especially during the
summer months. There
seems to be a pervasive
impression that the
field trip chair is
expected to lead the
majority, if not all, of
field trips. This is
simply not true. The
field trip chair
coordinates the field
trips. This includes
such simple tasks as
scheduling trips,
posting notices and
schedules of upcoming
trips in the newsletter,
filing liability
waivers, and soliciting
club members to lead
trips. Of course, you
can lead as many trips
as you like. Dennis
Gertenbach, Trick
Runions, Paul Boni, and
others have already
committed to leading one
or two trips each for
this coming summer. We
just need someone to
take responsibility for
coordination the effort.
The idea
behind a club such as
ours is that we gather
together to pursue a
common interest. In this
case our interest in
minerals, fossils, and
rock hounding. There are
a few simple jobs that
need be done in order to
keep the group
functioning. If you
haven't served on the
board yet, we'd love to
have your help. It's a
great way to get better
acquainted with the most
active club members and
develop friendships.
Experience is not
required. Interest will
do just fine.
One final
point; There is a big
advantage in being the
field trip chair. You
often get to go to the
sites that YOU want to
collect. Think about it,
then contact
Paul Boni or
Dennis Gertenbach.
We'd love to have you on
board.

Measuring Earthquakes
From Rockhounding
Arkansas- 1998, via
Diggins From Dakota -
April 2004
A
recording device called
a seismometer is used to
measure earthquakes. The
Richter Scale is what we
hear about mostly, and
scientists also use a
scale called the Moment
Magnitude.
The
Richter Scale: A very
important fact in this
scale is that as each
number goes up, the
earthquake increases 10
times * in power.
1. Felt
by instruments only.
2. Felt
by sensitive people and
sensitive animal. (10
times #1)
3. Felt
by many people- feels
like a passing truck.
(100 times #1)
4. Felt
by everyone; pictures
fall off the wall.
(1,000 times #1)
5.
Damage- may cause weak
walls to crack and fall.
(10,000 times #1)
6. A
destructive earthquake
in populated areas;
falling smokestacks,
etc. (100,000 times #1)
7. A
major earthquake causing
serious damage
(1,000,000 time #1)
8. A
disaster-a great
earthquake that produces
total destruction to
nearby communities (1906
in San Francisco-8.3)
(10,000,000 times #1)
9.
Lisbon, Portugal had the
highest ever in 1775 at
8.9, until Sumatra
earthquake of Dec 26,
2004, magnitude 9.0.
(100,000,000 times #1)
The New
Madrid Fault
Located
in the "Boot Heel" of
Southeast Missouri, the
town of New Madrid sits
on a major fault that
extends into Arkansas.
In the early 1800's, a
series of magnitude 8
earthquakes occurred.
Written accounts from
eyewitnesses to this
earthquake are quite
remarkable. The size of
this event leads
geologists to suspect
the New Madrid Fault is
a failed rift valley: a
place where the North
American continent
almost split into two
pieces. What we know
from history is that if
something geologic has
happened in the past, it
can happen in the
future. Earthquakes are
not a matter of if they
will happen, but when
they will happen.

Mammals - the Wimps of
the Dinosaur Age?
by
Dennis Gertenbach
Not
necessarily. Recently,
paleontologists have dug
up a new species of
carnivorous mammal that
roamed China during the
reign of the dinosaurs.
This creature was large
enough to feast on young
dinosaurs, which goes
against the prevailing
thought that mammals
during this time were
tiny mouse-sized
creatures that scurried
around in the
underbrush, hiding from
the dinosaurs.
Repenomamus giganticus
was more than three feet
long, about the size of
a large dog. However,
the fossil indicated
that it looked more like
a large badger and
probably weighed about
30 pounds. The length of
the jaw is about the
same as a modern fox.
The fossil represents
the largest Mesozoic
mammals ever found. A
second similar, but
smaller relative,
Repenomamus robustus,
was also found in the
same area of northern
China. This fossil was
about 15 inches long,
approximately the size
of an opossum. Both of
these fossil finds date
back 130 million years
This
second skeleton had the
bones of a baby
Psittacosaurus in its
rib cage where its
stomach was. The
dinosaur bones are from
a single individual and
some are still
articulated (connected
together), making it
unlikely that they were
washed there after the
mammal died. The
articulation of the
dinosaur bones, along
with the mammal's sharp
teeth, suggests that
Repenomamus tore its
prey limb from limb
before gulping it down
in large chunks. This
mammal's last meal was a
dinosaur, the first
evidence that some
mammals preyed on
dinosaurs.
****************
Cutting Spencer Opal
By Evelyn Cataldo
Reprinted from The
Rockhound Gazette 10/97
After
sawing the opal and
finding the narrow band
of color, lap down on a
180-grit diamond ripple
disc until the fire
begins to show. Use
plenty of water to keep
the opal cool. When the
fire begins to show,
move to a 600 fine
diamond lap and continue
lapping until you are
about half way into the
layer of fire. Dry the
opal and clean it with
alcohol. Next apply a
coat of fracture sealer
to the opal and let it
set under a lamp or in
the oven at 150 degrees
for 20 to 30 minutes.
Allow the stone to cool
and wipe off the
fracture sealer with a
clean rag. Do not clean
the fracture sealer off
with acetone or alcohol.
Now you are ready to
glue the backing
material onto the opal.
The best
backing material is
basalt or basanite. It
is good and solid and
less expensive than most
other material. Obsidian
is too brittle and is
also too transparent
when cut thin. Mix the
glue according to the
manufacturer's
directions. Epoxy 330 is
recommended. The glue
should be the crystal
clear type. If using a
two-part epoxy, roll the
two parts together
slowly. If you mix it
fast air bubbles will
develop.
Make sure
the backing material has
been cleaned with
acetone or alcohol if it
has been sawed in oil.
Coat the opal with
epoxy. If you hold it
under a light and tip
it, you will be able to
see any areas you may
have missed. Place the
opal on the backing and
press down firmly. This
will push any air
bubbles out from under
the opal. After the glue
has dried, saw parallel
to the backing material
allowing approximately
one-quarter inch again
between the backing and
saw blade. After some
practice, you will be
able to saw closer than
this.
Lap the
excess opal away, again
using the ripple disc
until the fire begins to
show. Then finish
lapping on the 600 fine
disc. Lap as thin as
possible. The opal
should only be as thick
as about two pieces of
newspaper. Make sure the
opal with backing is dry
and clean. Apply another
coat of fracture sealer
and heat as before.
Allow it to cool and
wipe sealer off with
clean rag. At this time
you will decide where to
place the quartz caps if
you are using the
pre-cut kind.
When the
piece is ready to apply
the quartz cap, mix the
glue and coat the start
with it. Again you can
see any areas you may
have missed by holding
it up to a light and
tipping it. Drop the
caps straight down onto
the start and press down
firmly. If there are any
air bubbles under the
cap, they will look like
bright silver spots. If
air bubbles are present,
remove the cap, apply a
little more glue and
replace the cap as
before.
Now you
are ready to finish your
stones. Take a
pocketknife and scrape
all the excess glue away
from the cap. If you are
using dop wax, make sure
the edge of the cap is
visible all the way
around the stone. Some
people dop their stones
with epoxy, also. Trim
as much of the backing
away from the stone as
possible. Start grinding
on a 600 lap at about 15
to 20 degree angle so
that you undercut the
cap. With a little
practice, you will be
able to trim just under
the edge of the cap
without touching it.
This eliminates having
to polish the cap. The
backing should also be
trimmed down to about
one-sixteenth of an inch
thick.
If you
are not using the
pre-cut caps, glue the
slab of quartz on the
start, mark out the size
of stone you wish to
make and cab just as you
would a piece of quartz.

Enhanced, Treated,
Heated, Dyed,
Stabilized, Created,
Irradiated: Fake?
By Deborah Pfianz (from
Rock Chips 6/01)
Gemstones
and semiprecious stones
hove been fiddled with
for centuries to make
them 'more' colorful,
more eye-catching, and
easier to work. This
does not make them
'fake'; however one
should know what some of
those terms and
treatments mean.
Heat
Treated: this is the
most common treatment
and is as old as fire.
Humans heated agate and
jasper so as to be able
to knap the stones for
tools. Humans also heat
gem material to enhance,
clarify or create color
in a stone. Amethyst is
heated for citrine and
ametrine. Zircon is
heated to clarify the
stone to clear white.
Sapphires are heated to
get the most amazing
pinks and blues.
Tigereye is turned blue
or red. Carnelian turns
orange-red Aquamarine
may go from green-blue
to blue. Rubies may lose
a purplish tint. Iolite
may be turned a deep
blue. It is also used to
enhance the 'color
change' gems such as
tanzanite.
Dyed:
this is also a very
common practice. Agate
is dyed to get fancy
pinks, purples, oranges,
and blues-eye catching
and very saleable.
Chalcedony is often
dyed; black is sold as
onyx and green is sold
as chrysoprase. Howlite
is often dyed to look
like turquoise, lapis,
sodalite and charite.
Turquoise and Jadeite
are often dyed to
enhance the natural
color. Alabaster, coral
banded calcite, and
marble are dyed to
enhance their color or
to imitate other
semiprecious stones.
Irradiation: while topaz
is currently the most
commonly irradiated
gemstone (to get various
shades and tones of
blue) this is also how
one gets those
fabulously colored
diamonds, In fact
diamond was the first
gemstone color treated
with radiation.
Stabilized Opals are
often stabilized-either
by filling such as with
Opticon resin (similar
agent) or by capping
either as a doublet or
triplet. Emerald has a
long history of fracture
filling due to its
popularity and its
tendency to be highly
included and fractured.
While natural oils hove
traditionally been used
for filling and
stabilization, modern
synthetic resins are now
being used, such us
Opticon, which are more
permanent than the
natural oils were.
Turquoise and coral are
also stabilized in such
a manner so as to make
them a bit more durable.
Created:
this is a touchy subject
for some folks. Much
like formed pearls are
real with a center of
plastic or mother of
pearl rather than sand.
Still real, still a
pearl just helped to
grow by a human.
Laboratory grown
crystals of ruby,
sapphire, diamond,
emerald and star
sapphire are real
semiprecious stones.
They just weren't grown
in the earth.
So what
is the answer: Real or
FAKE? This 'real vs.
fake' can be argued with
all sides being
technically correct.
That is not the most
important information
one can have. The really
important bit about this
from a lapidary or
jeweler's point of view
is disclosure. Does one
know up front that the
stone you are getting
has been 'helped along'
by the human touch? Do
you as a lapidary
artist, gemsmith,
jeweler, or craftsperson
know what you are using?
The beauty and art that
we create with these
stones is being helped
along by our touch, much
as it was to first get
our attention. There is
beauty in the knowing-be
sure to shore that with
those around you.

Minutes of the Board
Meeting - Nov. 29, 2004
Charlotte Morrison. Secretary
The meeting was held at
Charlotte Morrison's
house. Present
were Dennis Gertenbach,
Terry O'Donnell, Ray
Horton, Paul Ralston,
Alex Cook, Gerry Naugle,
Ray Gilbert, Lew Yoder,
Trick Runions, and
Charlotte Morrison.
Gerry Naugle has
prepared a complete
report on income and
expenses for our recent
club show. The
attendance was up, and
with expenses we still
added income to the
treasury. On a poll
taken as people came in
to pay they stated the
signs were more of an
attraction than the
newspaper
advertisements.
Gerry reported that we
got 12 new members at
the show, that we have
73 renewals thus far,
but that many have not
yet renewed. Thanks to
Emily Epstein for
selecting speakers and
instructors and printing
a program. Alex Cook
would prefer to have
someone else named show
chair. He will help.
Terry O'Donnell and Ray
Horton have many ideas
for our monthly club
meeting programs.
December will be our
annual gift exchange
party. Ray Horton
and Terry O'Donnell
requested a musical
February. Ed Raines is
lined up for our March
meeting.
We received a request
from Dinosaur Ridge to
contribute to their
membership. Dennis
called for the motion,
and it was seconded and
approved, that we would
join at the $100 level.
We will receive their
newsletters, two books,
and a place for field
trips.
Gerry Naugle, as
treasurer, moved that
more money for the
scholarship fund be
sheltered.The motion was
approved.
Alex Cook suggested that
we adopt an operating
budget to guide our
purchases and expenses.
There was discussion on
ways to decrease
expenses and increase
income. Our dues
structure does not pay
all of our expenses.
Trick Runions suggested
that we advertise the
e-mail delivery of the
newsletter on page 1.
Advantages are: color
photos, clickable URL's,
and the saving of trees.
Dennis would like to
table this item and have
the board members think
of new ways to earn
money.
The fact that we do not
have a field trip chair
for 2005 was discussed.
It was pointed out that
the field trip chair
would not be expected to
lead every trip, but
would coordinate trip
leaders and keep a box
of maps. Paul Boni
will write a message of
encouragement to get a
field trip chair or
committee. Dennis
will lead one or two
trips, and Trick one.
The club has acquired a
Cloud Dome for close up
photography. At
present, Emily Epstein
has checked it out.
There will be a list for
members to sign up for
it at the next club
meeting.
Dennis Gertenbach has
all the information for
the Junior Geologist
merit badges organized
by the American
Federation of Mineral
Societies. Dennis
obtained their 96-page
manual off of the
Internet. The
badges are free.
For the next board
meeting, Dec. 27, Dennis
suggests a potluck
dinner at his house,
1283 W. 27th Drive,
North Lakewood.
****************
Minutes of the Board
Meeting, Jan 31, 2005
Terry
O'Donnell as Vice
President called the
meeting to order at the
home of Caroline and
Alex Cook. Present
were Terry O'Donnell,
Alex Cook, Ray Gilbert,
Ray Horton, Trick
Runions, Shirley Mehta,
Paul Boni, Lew Yoder,
Gerry Naugle, Paul
Ralston, and secretary
Charlotte Morrison.
Terry
O'Donnell and Ray
Horton, program chairs,
have established the
next few months'
programs: February,
Valentine Party; March,
Ed Raines, a well-known
mining history expert
and member of several
clubs; April, Waverly
Persons, the
international earthquake
expert; May, Jack
Thompson from Colorado
Springs on Colorado
topaz (Colorado Springs
will host the Rocky
Mountain Federation show
in June.); and June, our
annual silent auction.
Gerry
Naugle gave the
treasurer's report. The
books are in order,
including the
pre-payments on tables
for our November show.
We have a letter from
the Scientific and
Cultural Facilities
District, and Gerry
Naugle will pursue this,
with the hope that we
may receive a grant from
SCFD for our activities.
Another
correspondence is from
the Boulder Ranger
District, concerning the
planning of trails in
Lefthand Canyon.
Trick took this letter,
and will discuss our
position with Cory Olin.
Alex Cook
and Gerry Naugle have
completed the 2004 audit
of the books. Alex has
made up a budget for
expenses we will have.
Expenses above the
revenue from annual dues
are made up with the
show and silent auction.
Discussion ensued about
setting the annual dues
at a different rate for
e-mail newsletter
subscriptions. Another
significant expense is
the rent to the City of
Boulder for our meeting
room. $800 was spent on
shop equipment. The
board is preparing a
plan for increasing
equipment in the
workshop when we earn
more money.
The
membership has been
purged of the old
members that have not
paid 2005 dues. The
mailing label count is
down to 62 from 78, with
a few members newly
requesting e-mail
delivery.
Paul
Ralston is thinking
about the next Life
Member award. At the
present this honor is
awarded every other
year, and Paul will
consult the bylaws for
the list of
requirements, to help
plan for the next award
in 2006.
Thanks to
Ray Gilbert for a
splitter box for
electricity at the
November show. Ray
Gilbert, librarian, has
enough new books and
magazines to update the
library list. We also
need to update the
property list.
Dorothy,
Ray, and Barry Knapp
will have refreshments
for the February
meeting, and Ray invites
any club member to bring
some appropriate
Valentines Day
refreshment. Do we have
a refreshment list for
the February meeting, to
keep track of the
refreshment boxes that
are taken home to a dry
place each month?
Alex Cook
has a letter from Ron
Knoshaug who will be the
field trip coordinator
for joint field trips
with the Mile Hi Rams.
The next board meeting
will be February 28 at
the home of Charlotte
Morrison.
