2.1" Galena, Quartz and Sphalerite Association - Bulgaria

This specimen displays galena in a variety of shapes and sizes, spread throughout the entire mineral aggregation. Clear quartz crystals line a portion of this specimen, giving it a slightly spiny appearance. Opaque black sphalerite can also be found in a couple places, protruding from the galena crystals beneath.

The Madan ore fields are located in the Rhodope Mountains of Bulgaria. This long stretch of mountain range in Southeastern Europe is home to a variety of incredible minerals, with sulfides being some of which show great variety in these mountains. One of these sulfides is gold ore, a mineral that is mined consistently from the Rhodopes, though is typically found containing relatively high amounts of cyanide. Because of this, there is an additional cyanide extraction process that takes place before the gold can be applicable for whatever use.
Other sulfides like galena, sphalerite, and chalcopyrite of all shapes and sizes, can be found throughout this mountain range.
