Improving Mindat.orgSearch by chemistry misses some

14th Feb 2018 00:11 UTCBruce Kelley Expert

When I do a search by chemistry for all IMA approved minerals containing Tl, I'm surprised that it does not find Galkhaite, with the formula

(Cs,Tl)(Hg,Cu,Zn)6(As,Sb)4S12

Is there good some reason for that, or is it a bug?

14th Feb 2018 03:05 UTCAlfredo Petrov Manager

Probably because it's only looking for "essential" elements, not substituting elements?

14th Feb 2018 10:54 UTCUwe Kolitsch Manager

It's because the search uses the IMA formula, (Hg5Cu)CsAs4S12.
