Dolomite with Quartz

specimen number:
2312143

location:
Shangbao Mine, Hunan, China

description:
Attractive pink rhombohedral crystals of dolomite measuring to 2.0 cm in size on a crystallized quartz matrix. In great condition and quite attractive. From 2008.

The Shangbao Mine, located in Leiyang, Hunan Province, China, was originally established as a tungsten and polymetallic deposit during industrial expansion in the mid-twentieth century. Geologically, the area involves complex skarn-related hydrothermal fluid interactions where Mesozoic granitic intrusions affected older sedimentary and Paleozoic strata. As mining progressed through quartz and calcite veins, underground operations uncovered significant pockets of non-metallic mineralization. The mine has since become internationally famous among mineral collectors for producing well-formed cubic fluorite crystals that frequently display distinct color zoning and phantoms, often found in association with quartz, pyrite, calcite, and dolomite.
