1600424aadwlnnr.a ((CALCITE with CHALCOPYRITE pseudomorphs after GALENA)), $10 MINIMUM BID, Sweetwater Mine, Reynolds County, Missouri, 6 x 4 x 4 cm, Miniature, | |
Here is a pair of undamaged double terminated Calcite crystals on a matrix of small white Dolomite rhombs. On the matrix are octahedral crystals that appear to be the octahedral Galena crystals but they are solid Chalcopyrite. I never seen these before but they must be Chalcopyrite pseudomorphs after Galena. |
