Geology Magazine?
21 messages in this thread
All,
Have been picking up a few mags lately and am wondering where I might find the
beast known as "Geology?" Is it a trade mag only, and is there an address? So
many of the article in "Earth" magazine refer to Geology, but I have yet to be
able to locate one.
Also, picked up the most recent issue of Rock and Gem, the one with articles on
"Canyon Country Leaf Fossils," "Wyoming's Famous Fossil Fish," and "Collecting
Fossilized Clams." I wonder does this magazine always have so many articles on
fossils, or is this a fluke? Are there any really good mags on fossils?
Thanks,
Shannon
Hi, Shannon–
That seems unusually many fossil articles for Rock & Gem, but 1 or 2 per issue
is normal. I am in CA this week, away from my collection; otherwise I would
glance at a few issues and make sure my guesstimate is correct.

Hi, Shannon and welcome to the forum.

Rock and Gem publishes 'theme' issues. This months issue the theme was
fossils, last months was lapidary how-tos, next month may be gold, beads, or
whatever. They always have several field trip reports. For leads on other
magazines you might be interested in check out GEOMAG.TXT (I think) in library
12 of this forum. I don't know if 'Geology' is in there – it's been a while
since I d'lded it and it gets updated from time to time.

Hi, Guy–
We have no magazine named Geology in GEOMAG.TXT
If anyone comes up with an address for it, please let us know.

Hi, Doug

Yeah, I hadn't downloaded it since last winter. Didn't know if it had been
updated over the summer or not.
I just got back from the FM outing at Washington Pass. Spent yesterday
clambering around road-cuts with a fellow (Corky) from the Seattle area. We
didn't know what we were looking for, but almost everything we brought back to
camp lit up under the SW lamp. It was gratifying to see the experts getting
excited! Lanny found some great stuff. He mentioned that he had promised you
some.
Whew! I've been on the road about seven hours today. Got a lot of catching up
to do…
Regards, Guy
Hi Guy, Doug,
I got back late Sunday, but have been up to my neck in getting caught up. It
was hot, the company was great, the collecting was poor, except for fluorescent
material, and the scenery was great.
Hopefully in the next couple of days I will get through those fluorescents and
get them ready and sent as promised.
We have more fires burning in Central Idaho, one rather close to where I wanted
to go next–prospecting in a reportedly vuggy stock. So, I may have to go to
Montana instead.
Lanny
Hi, Guy & Lanny–
I am pleased to hear you found some good (read "fluorescent" 🙂 rocks. I envy
you as I just got back myself, but it was a working trip that kept me too busy
to collect or visit here much. I managed a brief stop at the Fluorescent
Mineral Society, where Rod showed me the fluorescent ferrierite that was high
on my to-collect-in-CA list.
Were all the fluorescents zektzerite, or were there other minerals fluorescing
as well?

Hi, Doug

By and large the _Real Bright_ fluorescents were the zektzerite. They were
easily as bright as the opal I sent you last year. The feldspar (Lanny, help
me out here if I have this wrong) in the granite fluoresces a dim purplish
pink. I have one or two specimens that have patches of brighter pink, not sure
what that is. I need to get an industrial strength SW lamp. These 4 watt
battery units are great in the field, but don't cut it at home. Wish I'd taken
Joseph up on his unit.
Lanny, I stopped at the first road cut on my way home and collected at the side
of the road. I did turn up a few small blebs of zektzerite in those samples.
How did you guys do at the second road cut? I don't think I remembered to ask
you about the okanoginite. How does one identify that?
Cheers, Guy
Much of the feldspar fluoresces a nearly bright reddish pink. I don't remember
anything that I would have called a "dim purplish pink" although that just may
be the microcline activated at adifferent strenghts.
We didn't find much exciting where we were. There were some interesting,
unknown micros in the rock, haven't looked at them under the scope yet. After
three days of rugged hikes, I didn't have a lot of ambition Sunday and only
beat on the boulders for a couple hours and headed home.
The Okanoganite is micro–1-3 mm. Always in pseudotetrahedrons (orthorhombic
twins). Color is tan to pale pink. Generally they occur in groups– so far only
known from two boulders.

Hi, Guy–
Feldspar (typically microcline) fluorescing dim maroon is commonplace. I just
read in Manny Robbins' new book on Fluorescence that this fluorescence becomes
bright when it is chilled enough.
The zektzerite may fluoresce as bright as that opal, but I will wager it is not
the same green color. The books describe it as "white"; I suspect Lanny's
mention of "bluish" is also zektzerite, a variation on white.

You're right. I would call it bluish white – about the same color as Tide
laundry detergent (unscented).

(Back now from putting lump of granite in freezer. <g>) How much is 'chilled
enough'? Are we talking cryogenics here? I saw Robbins' new book in the Mt.
Press catalog that arrived today. They also carry Rudy Tscherichs' Zeolites of
the World, but I think I can buy that one cheaper from him in person at the FM
Symposium next month, get get it autographed to boot.
I'm still recovering from OzCIS self destructing last Sat. night. Lost all of
this sections messages in the process. I tried resetting the counter last
pass, but only got todays messages. I recall a message from Lanny stating that
the feldspar should be bright red. Maybe with more than 4 watts that's true.
I'm in the market for a more powerful SW lamp now. Wish I had jumped on
Josephs' when I had the chance.

Hi, Guy–
Manny chose maroon-fluorescing feldspars in particular for describing a home
experiment with a typical freezer. He recommends leaving them in there for
several hours and keeping a control – a piece of the same specimen or very
similar specimen kept out of the freezer – for comparison. The cooled
specimens often fluoresce "distinctly more brightly than reference specimens",
though this is liable to vary from one locale to another.
I think I have seen that OzCIS 1.1, when asked to change the high message
number (other than the automatic advance), does so _after_ normal fetching of
messages, but before custom operations, and will re-advance the high-message
number late in that session, unless that is also suppressed in the forum
configuration. You might try fetching the older messages using that custom
menu. Tell me what dates you missed, and I can send you a transcript.

So far, so good. That piece has been in the freezer for a couple of days, and
I have *lots* of control specimens. <g>
> Tell me what dates you missed, and I can send you a transcript.
Don't bother, I didn't miss anything – the messages were just overwritten.
Somehow the 'force purge' and 'overwrite msgs' flags were set. (Must have been
my evil twin. <G>) Messages are accumulating normally now. I only keep 15 days
worth of messages, so it won't take long to rebuild my collection.
Thanks, Guy
Doug,
I've disappeared here for a while, but shortly before I did I uploaded two
questions–one about fossils ID books, and this one about Geology magazine.
Wasn't able to be on for a week or so, then came back to find the fossil ID
gone and the geology mag question discussing a completely different agenda. Did
any replys scroll off? I didn't think the science forum did that kind of
volume. I'm really sorry to have missed/not thanked anyone who might have
replied. Any suggestions?
Shannon
Hi Doug,
It was a lot of fun, good sociallizing and rather rugged difficult collecting.
Three+ days of that usually requires one go on vacation afterwards.
See Guy's message and my response on the fluorescents, although I just
remembered that when Guy lamped my best piece there was something showing
bluish. I haven't dup them out of the box and looked at them yet. Might get to
it this weekend and mail you a zektzerite specimen Monday.
Lanny
Shannon,
"Geology" is a research journal published by some big academic-type house. You
can find it in most university libraries but not on your local
newsstand–sorry!
Alexandra
"Geology" is published by the Geol. Soc. of America and has a wide variety of
short professional papers. You might be able to subscribe but primarily it
comes to members of the GSA as part of membership.

Hi, Dick–
Would you (or anyone else out there) have an address for membership in the
Geo. Soc. America for inclusion in GEOMAG.TXT?
–Doug
Doug,
GSA's address is 3300 Penrose Place, P.O. Box 9140, Boulder, CO 80301. Phone
is 1-800-472-1988. I think that this is the main number so you would have to
ask for the membership or whatever department.
Hope this helps,
Alex
Hi, Alex and Don–
Thanks for the info! I have filed it in my list of additions for the next
generation of GEOMAG.TXT.
–Doug
Hi Doug,
