Calcite

specimen number:
9507050

location:
Leiping, Guiyang Co., Chenzhou, Hunan, China

description:
Chocolate brown rhombohedral crystals of calcite to 4.0 cm in size on matrix. A second-generation of colorless gemmy lustrous calcite is present. In good condition.

Leiping Mine in Guiyang County, Chenzhou, Hunan, China, is a localized mineral source best known among collectors for producing high-transparency optical calcite crystal clusters often anchored on a gossan matrix. Precise historical records detailing the exact opening and closing dates of the Leiping Mine are not widely documented in mainstream geological literature, though commercial mineral specimens from the site gained wider recognition through modern Chinese mineral exports. Geologically, the region sits within the rich Nanling metallogenic belt of southern China, where complex magmatic-hydrothermal activities, granitic intrusions, and fluid-rock interactions with Paleozoic carbonate sequences and limestone host rocks have driven the formation of diverse polymetallic, skarn, and secondary gossan environments conducive to crystal growth.
