Galena with Pyrite, Sphalerite

specimen number:
2312179

location:
Turt Mine, Satu Mare Co., Romania

description:

Fine twinned crystals of lustrous galena to 3.0 cm in size on a cluster of bright golden crystallized pyrite with sphalerite. In great condition. These are flattened penetration twins.

The Turt Mine, located in the Oas Mountains of Satu Mare County in northwestern Romania, is part of a historic metallogenic region with long-standing underground mining operations targeting base and precious metals. Geologically, the deposit is situated within the Neogene volcanic belt of the Inner Carpathians, where subvolcanic structures and complex hydrothermal vein systems cut through older formations. These fluid systems deposited concentrated pockets of lead, zinc, and copper sulfides. The mine has gained recognition among mineral collectors for producing fine specimens of galena, quartz, and distinctive pseudomorphs or crystal casts involving siderite replacing earlier carbonate minerals.
