From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

The high-grade metamorphic terrain of Hengshan located at the hinderland of North China Carton in northern part of Shanxi province, China, is a middle-lower crustal transition area of the typical continental crustal profiles of the Wutaishan—Hengshan—Datong—Jining of the early Precambrian etamorphic terrain in China.The Hengshan gneisses of the amphibolite—granulite facieses metamorphic terrain consist of the TTG gneisses and the horizontal adding mantle materials. The Supracrustal rocks in this area are composed of the mafic volcanic rocks and sedimentary rocks. The plenty of granitoid magma activities are the result of anatexes.
