Barite with Marcasite pseudo Pyrrhotite
Availability: 1 in stock
I chose this specimen due to its overall geometry. Two distinct 3cm crystals of barite are cemented in symmetry by host rock and have rosettes of marcasite replacing pyrrhotite. I also like the concave form caused by solution etching of the back of one crystal.
Locality: Rosebud Mine, Kamma Mountains, Pershing County, Nevada
