2.1" Galena and Chalcopyrite Crystal Association - Bulgaria

This specimen contains an aggregation of metallic galena crystals, surrounded by what looks to be small quartz crystals along the edge. This specimen displays matrix inclusions of chalcopyrite, which can be seen by looking at what could be considered the base of this specimen.

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.
