///Sujiquan graphite deposit occurrence in the Mongolian Gazelle Hill penthouse of biotite granite base of granite and amphibolite long granite base of the contact zone, constitutes an extension of the Northwest to felsic with mixed with graphite, lenticular ore body was irregular in the plane for the short axis-like or similar equiaxed, often in the main ore body near the small number of nested or small lenticular ore body. Ore more than a spherical structure, between the graphite balls of quartz and feldspar component of the compact felsic cement, in addition to graphite sphere, there are content ranging from coarse-feldspar, quartz and mica and so on. With their predecessors δ13C isotope analysis, a mineral that is organic carbon. The deposit belonged to magmatic origin, not metamorphosed origin.
