1. Introduction

We have picked up ten new subscribers for a total of 20; see the end of this
message for the full subscriber list.

I hope to see everyone at the Franklin Show.  God willing, I will be there from
Thursday late afternoon thru Sunday early afternoon; and I'll be set up as a
"Pond" dealer with a burgundy and black full-sized long-bed Chevy pick-up with
Maryland tags, two card tables together and covered with a sheet of flake board
or plywood, and a green "gazebo".  Please stop by and visit, especially those
of you I've never met.

A request to those of you who self-collect: after collecting at any of the
dumps, the Mill Site, or the Passiaic-Noble Pits, please e-mail me a report
of your interesting finds.


2. Old Business

In FrOg On-line #1999-01, I asked about the "List".  The following reply was
received by e-mail from Dick Bostwick and has been edited:

     From Mon Jul 19 02:45:06 GMT 1999


     1) "The List" (as distinct from other lists in lower case) is the F/SH
     species list.  John Cianciulli is the new keeper of The List.  I believe
     this was announced in the first FMM newsletter and would have been
     announced in the spring 99 PT.  It certainly will be announced in the
     next PT.

     2) My name has always been firmly affixed to the fluorescent species
     list and there has been no announcement of any change.

     3) It does occur to me that you might want to include John Cianciulli in
     your distribution list:

     He might be able to answer your question about the "unique" list.


     Dick Bostwick


During the Labor Day weekend, I talked to John as suggested by Dick; he (John)
continues to be the keeper of the list of minerals unique to the Franklin/
Ogdensburg area.

4. Franklin Show News

A new opportunity is being made available to collectors during the 1999
Franklin Show.  The Passaic and Noble Pits will be open to the public for
collecting for one day only: Sunday, September 26, from 10:00 A.M. to 3:00 P.M.
Admission is $10, for which you can take out 10 pounds.  You will be charged
$1 per pound for each additional pound.  You must sign a release and be at
least 13 to be admitted.  Recent finds here include feldspar group minerals
(probably including Albite), an apatite group mineral, a scapolite group
mineral, Calcite, Wollastonite, "Jeffersonite", Gahnite, a mica group mineral,
Hydrozincite, Willemite, an un-identified green-fluorescing mineral, Quartz,
Galena, Magnetite, Norbergite/Chrondrodite, Fluorite, and others.

The banquet and auction at this year's show will be Saturday, September 25, at
the Immaculate Conception Church.  Doors will open at 6:30 P.M.; serving should
begin at 7.  Tickets will be $13.50 per person.  It will be an Italian buffet.
Beer will not be available at the banquet, so you must bring your own if you
wish to drink beer.  The guest speaker will be Rock Currier; his talk is titled
"Hot For Underground".

Daily admission to the Franklin Show is $4 per adult, $2 per child.  Admission
covers the show, the "Pond", and the Franklin Mineral Museum.

Dealer fee for the "Pond" is $20 per table for one day, $35 per table for two

The proposed "Dark Pond" will not take place this year.

5. Thomas S. Warren Day

Saturday, October 16, 1999 has been made "Thomas S. Warren Day" in honor of the
man considered by many to be the "father of fluorescent mineral collecting."
This day is jointly sponsored by the FMS (Fluorescent Mineral Society), the
FOMS, the Franklin Mineral Museum, and the Sterling Hill Mining Museum.  The
following events have been scheduled:

9 A.M. to noon - FOMS field trip, Mine Run Dump at the Sterling Hill Mining
Museum.  Fee is $1 per pound.

10 A.M. - dedication of the new Thomas S. Warren Museum of Fluorescence in the
GeoTech Center (which is in the basement of the old mill site).  Tom Warren is
planning to be there with his daughter Virginia and her husband.

1:30 P.M. - FOMS meeting, Kraissal Hall at the Franklin Mineral Museum.  The
speaker will be Bill Mattison; his talk is titled "The Chilling Side of
Fluorescence".  The talk will include actual demonstrations of cold temperature
fluorescence using liquid nitrogen and mostly FrOg specimens.

6:30 P.M. to 9:30 P.M. - collecting in the Passaic and Noble Pits, and the Mine
Run Dump at the Sterling Hill Mining Museum.  A flashlight required for each
person.  Fee is $1 per pound.  FMS and Sterling Hill Mining Museum Foundation
members only.

6. Sterling Hill Collecting News

Claude Poli reports finding non-fluorescent marble unusually rich with densely
packed yellow fluorescing Wollastonite grains.  Some massive metallic grayish
mineral (Claude thinks this is Arsenopyrite) is also present.

7. Buckwheat Collecting News

Claude Poli reports an assemblage containing Quartz, a feldspar group mineral,
and an apatite group mineral.  The apatite blebs consist of small sub-
millimeter grains fluorescing pale blue and lilac under short wave.  The
combination of the two colors makes for an interesting effect.

Claude also reports finding Calcite with Willemite exsolution lamellae in a
black serpentine group mineral, and specimens of what looks like more brightly
fluorescing Willemite exsolution lamellae in less brightly fluorescing gemmy

8. Featured Specimen

This specimen, from Sterling Hill, features solid massive Hydrozincite.  It's
display surface is roughly the shape of a pie slice with an estimated central
angle of about 80 degrees and a radius of about 9 cm.  Three zones comprise
the display surface.

The zone nearest what would be the center of the pie consists mainly of massive
or extremely fine-grain Zincite with embedded Franklinite grains.  The zone has
a fairly straight edge 4 cm from the pie's center.  The Zincite has an opaque
rather dark orangy-red color in daylight.  Also embedded in this massive
Zincite are a few sub-millimeter grains of gemmy deep red Zincite.  By
examining the sides of the pie slice, it is determined that this Zincite zone
ranges in thickness from less than a millimeter to about 5 mm.  Beneath the
Zincite is white Calcite with embedded Franklinite grains and tiny irregular
rather dark orangy-red Zincite inclusions.  The white Calcite is visible on the
display surface within the Zincite zone in a few millimeter-sized spots near
one side of the pie slice, in a 5 mm spot at the pie's center, and in a few
other tiny spots here and there.

The next zone consists of massive Hydrozincite with embedded Franklinite
grains.  The zone has a rather irregular boundary with the third zone, and
averages about 2 cm in width.  In daylight, the Hydrozincite ranges in color
from pale tan nearest the zone's boundary with the Zincite zone to tan nearest
the zone's boundary with the third zone.  By examining the sides of the pie
slice, it is clear that this zone extends through the specimen as a layer
parallel to the bottom of the pie slice.  This layer is about 1 cm thick
nearest the center of the pie, and thins to about 1 millimeter along the
circumference of the pie.  There are a few millimeter-sized blebs of white
Calcite embedded in the Hydrozincite.

The third zone consists of an un-identified massive chocolate brown mineral
with embedded Franklinite grains.  This zone extends to the circumference of
the pie slice.  Also embedded in this zone are numerous white Calcite blebs a
few millimeters across, concentrated mostly towards one side of the pie slice.

The Franklinite grains are quite uniformly distributed throughout the specimen,
are mostly a few millimeters across, and have no regard for the zone boundaries
(so to speak).

Under short wave ultraviolet, the Calcite has its typical brilliant orangy red
fluorescence.  Now visible are numerous extremely fine hairs of Willemite
fluorescing brilliant yellowish green, running through the Franklinite grains.
In some Franklinite grains, the Willemite hairs have the appearance of
exsolution lamellae.  The Hydrozincite fluoresces pale blue, brightest along
the boundary with the Zincite zone, weakest along the boundary with the third
zone.  Under middle (312nm) wave, the Hydrozincite fluoresces cream along the
boundary with the Zincite zone, tan-brown nearest the third zone.  The long
wave fluorescence is paler and a little brighter than under middle wave.  Long
and middle wave also reveal a faint yellow-brown fluorescence in the Zincite
zone, suggesting the Zincite grains may have a very thin coating of secondary

Have a neat FrOg specimen?  E-mail me a description of it.  In the description,
first introduce the specimen, highlighting what's special about it.  Describe
its appearance in natural light.  If fluorescence is relevant or interesting,
describe the specimen's fluorescence.  The specimen need not be fluorescent,
and it need not be unique to be featured here.
