Calcite with Quartz, Hematite

specimen number:
2312609

location:
Ocna de Fier, Severin Co., Romania

description:

Blocky rhombohedral colorless crystals of calcite to 3.0 cm in size across and andradite crystal matrix with hematite. Quartz is present as well. In great condition.

Ocna de Fier, located in the Cara--Severin County of western Romania, is one of the oldest and most historically significant mining districts in Eastern Europe, with iron and polymetallic extraction dating back to Roman antiquity and experiencing extensive commercial operations through the Austro-Hungarian period into the modern era. Geologically, the area is characterized by a classic skarn deposit where Cretaceous granodiorite and banatite intrusions invaded older Jurassic limestone and metamorphic sequences, creating intense contact metamorphism. Mineralogically, this complex geological setting fostered the formation of an exceptionally diverse array of over one hundred mineral species.
