Fluorite with Barite

specimen number:
9506764

location:
Jiang Jun Gou, Huairou, Beijing, China

description:

Attractive golden yellow semi lustrous mostly gemmy cubic crystals of fluorite to 3.7 cm in size on a barite crystal matrix. In good condition with very minimal and tiny micro-damage present.

Jiang Jun Gou, located in the Huairou District on the northern mountainous outskirts of Beijing, China, is tied to fluorspar workings originally discovered in the early 1940s and operated intensively during the mid-1940s, before experiencing subsequent phases of revival and eventual abandonment. Geologically, the deposit sits within the Yanshan Fold Belt on the northern margin of the North China Craton, where hydrothermal fluids circulating through fractures in Jurassic volcanic rocks deposited fluorite and associated minerals. The striking specimens from this locality feature sharp, golden-yellow to honey-colored cubic fluorite crystals nestled on or intergrown with a matrix of white, crystalline barite.
