[Rockhounds] Cactus Calcite

[Earl R. Verbeek]

Yerington, not Verington.  I don't know if there's anything on MinDat
about that district, but I'll look.  What you describe sounds like some
calcite I've seen from Mexico, but Mexico is a BIG place.
 
Not much help, sorry....
 
            Cheers-    Earl

Subject: [Rockhounds] Cactus Calcite
 
List: I have acquired some 2 dozen unusual Calcites from an old
collection. 
These are labeled;
 
Cactus Calcite
Verington District
Lyon county
Nevada
 
Both the specimen habit, and the locality are new to me, and I wondered
if 
anyone has any information they can add. The pieces are very sharply 
terminated crystals, finely grouped in masses up to 6X10 cm,
cactus-like, 
and are very delicate and pin-point sharp. There is very little matrix, 
which appears to be massive tan to cream colored Calcite. The owner told
me 
these were collected over 40 years ago.
 
I'll post some pictures when I get time, but I would like to know more
about 
the locality and the geologic environment, if possible. (there is little
on 
the web, but some about the habit on web databases).
 
 
Thanks.....Larry
