a Talk
by
Robert Verish and Ron Hartman
"METEORITES
OR METEOR-WRONGS?"
"Calling All Meteorites!!"
MAY
PROGRAM
This
months special guest lecturers are Robert Verish and Ron Hartman. They
will be presenting a program on the identification of meteorites.
Mr.
Verish, who works as a contractor for JPL's Deep Space Network (DSN), is
one of the few people who has found, and eventually identified, a rock
from another planet - two pieces of a meteorite - composed of a type of
rock from Mars known as a shergottitic basalt.
While traveling home from his work site at NASA's Goldstone
Tracking Station in the Mojave, Bob would take side trips to do some
rockhounding. Over the past
20 years he has amassed a large collection.
On one of these side trips, Bob picked up and took home some
odd-looking, glassy rocks. At least 18 years would pass until he would
see these rocks again while cleaning out his rock collection.
In the intervening years Bob had earned a degree in geology from
Cal State University at Los Angeles and developed an interest in the
space sciences. Upon
recognizing the rocks as being possible meteorites, he took samples of
them to the Cosmochemistry Lab at UCLA, where their analysis eventually
would show that these rocks had come from MARS!
Bob,
also known on the Internet as "Bolide*chaser", has recently
appeared in a segment of "Hunt For Amazing Treasures" on The
Learning Channel. This video segment is a mini-documentary about his
recent pursuits to try and find the original location and more of the
Mars rock meteorite that he found while rockhounding.
Although Bob hasn't found any more Mars rocks, his efforts have
resulted in several other new, stony meteorite finds for California and
Nevada. Currently in his spare time, Bob is the Principal Field
Investigator for the Meteorite Recovery Foundation.
Ron
Hartman is Professor of Astronomy at Mt. SACC, Walnut, CA.
He is in charge of that school's Planetarium.
He regularly presents shows to all grades of science classes and
tours. In the lobby of the Planetarium are several displays of
meteorites, all from his personal collection.
The school kids are always quite impressed, since these displays
rival those at the Griffith Observatory.
Ron
is noted as being the first person to have gone to a desert dry lake to
purposely LOOK for meteorites, AND (on his first trip) to actually FIND
one. Later, he found
several more. He published
a paper in 1964 based upon these finds, which are now called the Lucerne
Valley Meteorites. In 1999,
36 years after making his first find, Ron found the 17th Lucerne Valley
Meteorite. Ron Hartman along with his son, Jim, are noted meteorite
specimen preparers. Their
web site is: http://www.themeteoritesite.com/
Bob
has offered to inspect any and all suspect meteorites. So come to the next meeting and bring your 'space rocks' with
you.
FROM THE EDITORS DESK
If
the speaker listed in this Bulletin seems familiar, he is.
Due to a misunderstanding there was no speaker at the last
meeting. Robert
Verish has kindly consented to give his presentation at the May meeting.
As you can see, he has added Ron Hartman as his associate.
PRESIDENTS COLUMN
by Dave Smith
As
I indicated in the March meeting, I consider the filling of the
Committee chair positions of the utmost importance for this society. It
is fairly difficult to sell these positions because we haven't always a
clear idea what duties each position entails.
Most of these positions don't require a huge amount of time or
work from an individual.
I
would like to compile descriptions of these tasks and make them
available for the membership to read.
This task has been undertaken before and many of these
descriptions currently exist. The
problem has been a lack of a durable repository for these valuable
documents.
I
have spoken with our Webmaster, Bill Besse, and we have agreed that
these descriptions could easily be incorporated into the web page,
giving us a location to retain the information and provide the most
accessibility possible at the same time.
I
would like to request anyone that has any of these descriptions to send
them in to me, or the society. Additionally,
if some of our fine members who have held these positions in the past
could write up what they used to do as part of their job, we could
utilize that input to create descriptions for any positions that don't
have one written up yet.
This
society was described by one of our most recent life member honorees,
John Sinkankas, as "the most active and productive earth science
organization in America". In
order to live up to such high praise, we need to reactivate these
essential functions and I consider this to be the first step.
We will revisit this topic in future Bulletins for updates and
some previews of some job descriptions of chairmanships we would most
like to fill.
CFMS 2001
SHOW
Greetings from Santa Lucia
Rockhounds
Bea
and Sherm Griselle, Co-Chair Show Committee-2001
The
Santa Lucia Rockhounds, the host society for the CFMS 2001 Show, is
pleased to welcome you to the Federation's 62°d Annual Gem, Jewelry,
and Mineral Show. As you meet in Paso Robles, we are confident you will
thoroughly enjoy a splendid three-day show. Come and meet with hundreds
of other gem, jewelry, and mineral enthusiasts who will gather at our
California Mid-State Fairgrounds.
The
three-day show will feature over 150 excellent exhibits of some
magnificent minerals, fossils, petrified wood, gems and jewelry. You
will learn from demonstrators experienced in lapidary arts, fossil
preparation, and use of tools and machinery utilized by rockhounds.
There will be an extensive youth education and games area for young
people. There will be 50 dealers offering a wide selection of quality
items for sale to amateur rockhounds and experienced collectors. Attend
the free Cracker Barrel get-together on Friday evening, which is open to
all and will be an entertaining evening. The Banquet Saturday evening
promises to be a very congenial event this includes the presentation of
awards. The Editor's Breakfast on Sunday morning will be educational and
entertaining and is a "must attend" for all society bulletin
editors.
Extend your visit while you are in
Paso Robles so you can enjoy our magnificent Central Coast with its
natural attractions. Our beautiful rolling hills and valleys hold
historic small towns, rivers and lakes, gorgeous oak forests, dozens of
vineyards with wine tasting opportunities, golf courses, and ocean
beaches, fishing, and cruises. Other attractions include California
Missions, Hearst Castle, and the coastal towns of Cambria, Cayucos, and
Morro Bay. The area's restaurants, motels, and mobile home parks are the
best.
Get
your Calendar 2001 out and write-in the CFMS 2001 Show, June 22 / 24,
along with some extra days to visit our Central Coast and its many
entertaining, historic and educational places and activities. I know
that when you return home you will take with you wonderful memories of
the show and your visit to the Paso Robles area.
MEMORIAL DAY WEEKEND FIELD
TRIP
The Blanchard Mine, Bingham
New Mexico
Carolyn
Seitz will be hosting a field trip to the Blanchard
Fluorite mine over the Memorial Day weekend, May 26, 27, & 28. Some
of the finest fluorites in the world have come from The Blanchard.
In addition to fluorite, it is also possible to find galena,
selenite, smoky quartz, amethyst,
wulfenite, linarite, brochantite
and other minerals.
The
flyer in the center of the Bulletin gives more information on the trip.
For more reading on The Blanchard Claim, see Mineralogical
Record's New Mexico issue - Volume 20, #1.
You can also visit Bob's Rock Shop online and their posted
information about New Mexico collecting. The website is :
www.rockhounds.com/rockshop/nmsites.html
If
you plan to attend please contact Carolyn by e-mail (cmseitz@mindspring.com) no later than Monday, May
21 with information about the number of people in your party and your
expected arrival time.
The
easiest route is via Interstate 40 to Albuquerque, South on Interstate
25, then east on US 380 to Bingham.
The distance from Pasadena City College to Bingham is 900 miles
with a driving time of 13 hours 45 minutes.
This assumes no stops and an Interstate speed of 70 m.p.h.
Your time will vary depending on stops, and speed.
There are several attractions along the way such as the Grand
Canyon, Meteor Crater, and the Petrified Forest.
In addition, if time allows, we recommend that you make plans to
visit the New Mexico Museum on the campus of New Mexico Tech in Socorro.
What: We will be collecting at
the very well known Blanchard Mine over Memorial Day weekend. Some of the
finest Fluorites in the world have been found at The Blanchard. We will be
collecting on the dump, in many exposed cut areas and it is possible the
mine owners will allow collecting underground. MSSC does not sanction
underground collecting at any time. If you choose to collect underground,
you will do so at your own risk.
Accommodations: Dry camping is
available at the base of the mine. You must bring all of your own
supplies, food and plenty of water. There is room for RV parking and
tents.
Children? Yes, you may bring
children on this trip, but they must be well supervised and well under
control.
Safety Equipment: Hard hats and
miners lights are a must for underground collecting. For collecting on
the surface, sunscreen, wide brimmed hats and gloves are recommended.
Fluorite collecting is always hard rock mining. Bring appropriate
collecting equipment hammers, chisels, gads, pry bars, etc. No power
tools will be allowed.
Snakes? Yes. Rattlesnakes are
common in this area. No scorpions have ever been observed. Please do not
bother the snakes and please do not kill or injure them unless you are in
direct jeopardy. They serve a valuable purpose in this micro-environment.
Weather: You can expect daytime
temperatures to be relatively high as much at mid 90s. Be prepared
for cool evenings as it cools off quickly when the sun goes down.
Vehicle Access: High clearance
four-wheel drive vehicles are a must for access to the collecting areas at
the Blanchard. They are not necessary for access to the dry camping
area.
Cost: The cost for collecting
will be $5 per day per person. All persons in your party are expected to
pay this $5 per day in cash - even if they are not directly involved
in collecting activities. There will be no exceptions.
Mandatory Meeting: All people
who wish to have access to The Blanchard for any or all of these three
collecting days must be at the Blanchard Rock Shop in Bingham, New Mexico
at 8:30 am on Saturday, May 26 to complete liability waiver forms and pay
the collecting fee. If you do not think you can make it to the Rock Shop
on Saturday morning, but expect to attend this field trip on Sunday and/or
Monday, please make advance arrangements with Carolyn Seitz. PLEASE
NOTE: PROOF OF CURRENT MEMBERSHIP IN THE MSSC MUST BE PRESENTED TO CAROLYN
SEITZ PRIOR TO COMPLETION OF THE LIABILITY WAIVER FORMS. NO ACCESS TO THIS
FIELD TRIP WILL BE ALLOWED WITHOUT PROOF OF MEMBERSHIP IN EITHER THE MSSC
OR ANOTHER CFMS MEMBER CLUB OR SOCIETY. THERE WILL BE NO EXCEPTIONS.
After all paperwork is completed at the
Rock Shop in Bingham, we will caravan to the collecting site. At the
collecting site, there will be a mandatory safety meeting before
anyone is allowed to collect.
If you are planning to attend, please
inform Carolyn Seitz, email at cmseitz@mindspring.com,
no later than Monday, May 21 with information about your expected date and
time of arrival in Bingham and the number of people in your party.
CAVEAT: The claim owners
for The Blanchard have made a request that no mineral dealers be allowed
to participate in this field trip. Since they will not expect us to pay
for the specimens we find on their claim, they do not want to be faced
with having to compete with dealers when they are ready to sell their
material. We have agreed to respect this request.
COLLECTORS
NOTES
The Olgiby Kyanite Quarry
by Walt Margerum
While
kyanite is the main reason to go to the quarry, there are many other
minerals to be collected if one is willing to spend some time and
effort. Most are found in
small amounts, and are not spectacular, but some are rare and unusual.
The following minerals can be found in the deposit; kyanite, limonite
(goethite) pseudomorphs after pyrite, magnetite,
specular hematite, rutile,
pyrophyllite, wollastonite,
and scorzalite.
The
Quarries were operational intermittently from 1925 throughout the
1950's. They were initially
operated by the Vitrefrax Corporation, hence the name for the formation,
and then later by the Aluminum Silicates Corporation of Los Angeles.
The ore was milled near the quarry, at the Blue Bird Mill, and
the concentrates shipped for further refining.
Total production exceeded 10,000 tons valued at more than
$80,000. The kyanite area
is presently inactive, and there are no signs of recent operations.
It should be noted that the American Girl gold mine claims are
very close to the kyanite area. The
cyanide leach pits are clearly visible, and should be avoided.
Most of the kyanite was mined from the taller hill, called Blue
Bird hill, but there was a small amount of mining on the shorter hill
just to the North. I will refer to these as the main hill and the small
hill.
Kyanite
is found as light to dark blue bladed crystals up to 2 inches long in a
matrix of granular Quartzite. The
crystals are rarely terminated and interlock to form a compact mass.
It is also found as a light gray material in one area of the main
hill. Scorzalite
is found as small dark blue to blue black inclusions scattered in the
Kyanite. There is no obvious crystallization. Magnetite is found
between the Kyanite crystals and also filling fracture zones in the
Kyanite. It is shiny black,
magnetic and shows an occasional crystal face, but no complete crystals
were found. The hematite
found here is specular, that is it is shiny black, and can be
distinguished from the magnetite by its lack of magnetism.
It is found under the same conditions as the magnetite, leaving
me to believe that one is the alteration product of the other. The pyrophyllite
is greenish white, and is found as radiating clusters of crystals to 1
inch in association with the sericite.
It is uncommon in this deposit, but was found in abundance at
Micatalc Hill inside the American Girl claims.
Limonite (goethite) pseudomorphs of pyrite are found in one area of
the main hill. They are
brown to yellowish brown, and range in size from less than a quarter of
an inch to greater than an inch on a side.
The original pyrite formed as cubes in the quartzite, and was
later altered by weathering to limonite.
I have tentatively identified them as goethite based on their
streak and color, but this is only an educated guess.
My
best specimens of kyanite were found in one of the many pits scattered
about the small hill, as were the specimens containing, scorzalite,
hematite, and magnetite. I think the reason for this is that the
deposits are less pure in this area.
Most was found on the south side of the hill.
This same area also has several
pockets containing sericite.
The magnetite, and hematite were found on the east side of the
hill.
I
found a 1 inch limonite (goethite) pseudomorph of pyrite as float in the
wash near the main quarry, and removed several others from an area about
half way up the main hill on the side facing the road.
Look for rusty brown quartzite containing holes where limonite
crystals have either fallen or weathered out.
Breaking open these pieces may reveal the limonite which most of
the time breaks clean. It
is hard work so it is best to spend some time looking for float before
trying hard rock mining.
Small
amounts of wollastonite can be found as float
at the base of the main hill on the side away from the road.
MINUTES OF THE APRIL 2001 MEETING
The
April meeting was called to order at about 7:45. Unfortunately the speaker for the night was unable to attend.
The minutes of the March meeting were approved unanimously.
Comments were then requested from the participants.
Jim Schlegel stated that the Pasadena Show is progressing
satisfactorily, and reiterated
his need for help. He then
talked about the Field Trip to Crystal Ridge, and showed some nice
specimens of quartz that he has collected from that area.
Several people expressed interest in the area.
Carolyn
Seitz announced that she will be conducting a Field Trip to the
Blanchard Mine at Bingham, New Mexico over the Memorial day weekend, May
26, 27, & 28. Various
collecting areas were then discussed.
Larry Bruce asked about pegmatites in the Atolia area.
If anyone has information on them please contact him at exoner8r@earthlink.net.
The meeting adjourned about 8:45.
