Located in the southern of Erlian-Hegen mountain belt, Bilugangan is a newly discovered Mo deposit of large scale in the center section of Inner Mongolia. Molybdenum mineralization occurs within the Indosinian granite stock or along its contact zone with Permian strata,consisting of veins, veinlets. The exposed stratigraphic unit is the upper Permian part of the Linxi group which mainly composed of dacite,sandstone, crystallinoclastic tuff et al. Magmatic activity occurred in the center district with northeast direction(Fig.1). The Indosinian magmatic units include granite, graniteporphyry. The texture of the ore-bearing granite is porphyriticlike. The typical major constituents of granite are present that phenocry:feldspar、quartz (~25vol.%) , parent: plagioclase (~20vol.%)、feldspar (~20vol.%)、quartz(~30vol.%)、biotite (~5vol.%).There are 3 rich molybdenum ore section in the mining area, the molybdenum mineralization occurs in the granite and hornstone.
