4.2" Galena on Quartz With Pyrite - Bulgaria

This is an aesthetic cluster of Galena cubes with Pyrite and Quartz from the Mogila Mine in the Madan ore field of Bulgaria. The specimen is 4.2" wide and the largest galena cube is .63" across.

The Madan Ore Fields have been known since the middle ages, being a big source of lead and zinc in the Middle Ages, and mined extensively in the past 50 years. There are more than 40 underground mines, and in addition to the ore, sometimes spectacular pockets of sphalerite, galena, chalcopyrite and pyrite crystals are discovered.
