The Shahongshan area, located between the Qiyishan area of Ejina Banner, Inner Mongolia, and Jinta County, Gansu Province, has numerous fluorite deposits, though on a relatively small scale.
The Middle and Upper Silurian Gongpoquan Formation is widely exposed in the exploration area. From bottom to top, it consists of carbonate rocks, terrigenous clastic rocks, and intermediate volcanic lava-pyroclastic rocks, creating an overall volcanic dome structure. Devonian and Triassic granites are well-developed in the area, mostly occurring as stocks and dikes, intruding into the Gongpoquan Formation. Tectonic activity is intense, with well-developed folds, faults, joints, and cleavages. Northeast-trending faults and north-northeast-trending faults are the two primary fault systems. The northeast-trending faults are compressional, while the north-northeast-trending faults are compressional-torsional, providing favorable mineralization conditions. Through systematic exploration, 38 fluorite ore bodies, 36 tungsten ore bodies, and 6 molybdenum ore bodies have been identified throughout the area. Fluorite ore bodies are allogeneically coexisting with tungsten and molybdenum ore bodies, and their spatial distribution is clearly controlled by tectonic forces, with the north-northeast-trending fault structure being the primary ore-controlling structure. Fluorite ore bodies range from 50 to 812 meters in length and 0.87 to 46.80 meters in thickness. The average thickness of a single ore body is 1.79 to 1.81 meters, with a thickness variation coefficient of 59.43%. The maximum controlled depth is 347 meters. CaF2 grades range from 27.13% to 97.28%, with an average grade of 56.29%. The ore bodies exhibit vein, lens, and vesicle formations, with ore structures primarily consisting of massive, banded, geode-like, and breccia-like structures.
