Hello Michael!

Congratulations to your exellent specimens and photos! I like this Cornish Cerussite and especial the Hematite from the Cavradi gorge. Theo Vencin is a well known collector/"Strahler" here in Europe.

Martin


Thank you Martin,
I was very happy to find the cerussite in Tucson last February. I had never seen one from that location at any of the shows I have attended.

I was reading the latest issue of Mineralogical Record, where there is a review of a new book on Cavradi. Mr. Venzin is mentioned as one of the authors. I will have to purchase a copy; it looks like it will be interesting reading.

Hi Michael,

I agree with our guys, you really do a good job in showing minerals both from famous localities and from places rather unknown (especially in the U.S.), one of my favourites is the wonderful pyrite from a Pennsylvanian locality I never heard of ( https://www.mineral-forum.com/message-board/viewtopic.php?p=40372#40372 ), I like the cubic crystals on matrix.

Great stuff, please more!

Many thanks, Tobi. The French Creek mines, where the pyrite is from, is a well-known U.S. locality, but has been defunct for nearly 90 years. Iron ore was discovered there in 1845, but the ore was mostly exhausted by 1926, and the mines closed in 1928. Specimens of chalcopyrite, pyrite, and magnetite from French Creek are often seen in old U.S. collections, but probably less so outside the U.S. An interesting side note is the fact that Charles Wheatley, the mine manager at the famous Wheatley Mines in Chester County, owned the Jones Mine, one of the two mines at French Creek.

I thought the name kammererite was changed to chromian clinochlore.

Hi Susan,

It may well have been changed, it's hard to keep up with all the name changing these days. I checked the most recent Fleischers that I have (2008) and neither chromian clinochlore or kammererite is listed as a variety of clinochlore. That being said, most longtime collectors still know this colorful mineral by the name that Nils Gustaf Nordenskiöld gave it in 1841 in honor of August Alexander Kämmerer.

Thanks Don. If you have Min. Record Vol. 40, #6, there is a good article about the pegmatites where these heliodors were found. Photos of some of the finer and larger crystals are fantastic.

Regards,
Michael

Thanks Pierre,
What's interesting is the varied morphology and color of celestine from this deposit. The crystals can be thick and blocky to needle-like, and they can vary in color from water-clear, to white, amber, and blue.
