Calcite with Sphalerite, Chalcopyrite, Quartz
specimen number:
2312167
location:
Boldut Mine, Cavnic, Maramures Co., Romania
description: The Boldut Mine, situated in the Cavnic mining district of Maramures County, Romania, is part of a historic polymetallic extraction center with roots dating back centuries. Geologically, the deposit lies within the Neogene volcanic belt of the Eastern Carpathians, where complex hydrothermal vein systems cut through volcanic and sedimentary host rocks. These epithermal solutions deposited rich concentrations of lead, zinc, copper, gold, and silver ores. Beyond its industrial mining history, the Boldut Mine is internationally famous among mineral collectors for producing magnificent specimens of quartz, rhodochrosite, and carbonates in association with various sulfide minerals such as pyrite, sphalerite, and galena.
Very fine combination piece with lustrous twinned black crystals of sphalerite hosting colorless crystals of calcite. Quartz and chalcopyrite present as well. In great condition.
