Fluorite

specimen number:
9506713

location:
Yindu Mine, Inner Mongolia, China

description:

Glassy translucent quality bluish green color zoned crystals of fluorite measuring to 3.5 cm in size on matrix. In good condition.

The Yindu Mine, located in the Hexigten Banner of Chifeng City, Inner Mongolia, China, is a modern commercial and collector mineral locality that gained prominence in the late 1990s and 2000s for producing exceptional polymetallic specimens, though specific regional mining operations have since seen limited active phases or exhaustion of fine crystal pockets. Geologically, the deposit is situated within the complex tectonic framework of the Great Xing'an Range and is classified as a silver-lead-zinc (Ag-Pb-Zn) polymetallic ore system. Mineralization is typically hosted in Mesozoic volcanic-sedimentary strata and intrusive-related hydrothermal environments, yielding notable associations of quartz, sulfides, and striking purple fluorite crystals.
