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 geological and geophysical data show that in the lower crust of young continental tectonic units may occur pervasive, non-seismic, subhorizontal and ductile flow related to thermal softening. The laminar flow drives fault-block movement of the upper crust, results in the formation of orogenic belts and sedimentary basins, and causes coupling between ductile lower crust and brittle upper crust/mantle.

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on.
