Sphalerite Var Marmatite and Pyrite
Marmatite is an iron rich variety of sphalerite. Here it is shown in as euhedral lustrous black crystals in an aesthetically pleasing combination with contrasting brassy pyrite. Not a rarity by any means from this locality which is well known for both minerals in Colorado, but a pleasing specimen nonetheless for its quality of both species. Minor coatings of chalcopyrite are observed on some of the pyrite under a microscope.
