Calcite

specimen number:
2312028

location:
Herja mine, Maramures Co., Romania

description:
A neat crystallized stalactite of colorless rhombohedral calcite crystals. Thick and terminated nicely, in super condition all around. Unusual and quite nice for the locality.

The Herja Mine, located in Maramures County, Romania, within the Baia Mare metallogenic district, is a prominent polymetallic hydrothermal vein deposit. Its geology is closely tied to Neogene post-collisional volcanism and subvolcanic intrusions, which created an extensive network of over 260 complex veins hosted within sedimentary and volcanic formations. Mining activity in the surrounding area dates back to the Middle Ages, with industrial extraction focusing heavily on lead, zinc, copper, and silver ores. The mine gained international recognition among mineral collectors for its diverse assemblage of hydrothermal minerals, including distinct stibnite clusters, sulfosalts, and rare bicolored calcite spheres. Commercial operations at the site permanently ceased in 2005, closing the underground infrastructure.
