14jkwg.is ((ANTLERITE, SERPIERITE, GYPSUM)), $30 MINIMUM BID, Jomac Mine, San Juan County, Utah, 7 x 4 x 1 cm, Cabinet | |
Collected by Wes Gannaway. Both Antlerite and Serpierite are copper sulphates. One darker green than the other. I'm not sure which one or both are present. My guess is these are mostly Antlerite, Serpierite is more fibrous or acicular. There are only 3 photos on mindat.org. White is a Gypsum seam. ex Wes Gannaway collection #1522. |
