PhotosUnid carbonate from Sterling Hill
1st Feb 2012 20:59 UTCModris Baum 🌟 Expert
It IS a carbonate – it dissolves completely with effervescence in HCl.
I don’t think it’s dypingite, which is, in any case, a Mg carbonate and was identified in 1979. If I remember correctly, dypingite forms “tracks”, is fluorescent and has a radial structure. This stuff doesn’t do any of that.
Anyone know what happened with the supposedly “new” Zn carbonate – or what this stuff might be?
Thanks - Modris

I think they were saying new to SH. But I'm not sure - I wasn't "in the loop".
Anyway - can't be a zeolite. Fizzed away completely in HCl. Maybe it's just weird calcite ...

Several years later, John Cianciulli (then curator at the Franklin Mineral Museum) and I worked on the material from an optical and chemical standpoint, and we offered material to John Rakovan for description and eventual IMA submission. However, John was unable to carry it all the way through due to the minute size of the crystals we had. Today, it remains an unnamed phase, awaiting some researcher who is willing and able to tackle it anew.

Most fascinating!
Well - if anybody wants to work on it I probably have about 10 samples.
In the mean time, it seems that Mindat already has an entry for UM1986-10-CO:ClHMgMnZn which appears to be the same as "Mineral F" (same formula), so I'll try to post it under that.
Guys - that was really fast and amazing!
Thanks - Modris

Well - it sure sounds like it!
I didn't realize it was in Dunn's monograph - or that he described it it as early as 1986. But that's probably about the right amount of time for the "rumor" to reach me.
Anyway - I do think you have probably nailed it again!
OOPS - I hit the send on my reply to Tony before I hit the send on this. Didn't mean to ignore you Jeff!

Have you been in my garage??? How did you know about those boxes I keep there!
