Quartz with Fluorite
specimen number:
2312260
location:
Huanggang Mines, Inner Mongolia, China
description: The Huanggang mines in Inner Mongolia, China, discovered in 1986, represent a super-large skarn-type iron and tin polymetallic deposit located in the southern Greater Khingan Range. Geologically, the deposit was formed during the Early Cretaceous period through intense contact metasomatism and fluid-rock interactions where post-magmatic hydrothermal fluids from Yanshanian granitoid intrusions invaded and reacted with Permian limestone and carbonate strata. This complex geological setting produced extensive skarn zones characterized by rich assemblages of garnet, pyroxene, magnetite, and cassiterite, making the location world-renowned for both its economic metal ores and exceptional mineral specimens.
Impressive large grouping of lustrous translucent quartz crystals with minor fluorite. Complete all around, this is in super condition.
