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.

文中对地幔交代流体组成、性质、活动特点及其成岩、成矿作用作了综述与探讨；从锡矿山区域壳幔结构和成矿背景、地质构造-岩浆活动史、高锑地球化学场结构分析、矿床特征、成矿物质(包括Sb、C、Si、S、流体及伴生元素)、与成矿有时空联系的暗色脉岩等方面入手，利用地质、地球物理、地球化学手段多方面论述了矿床与地幔交代流体活动的关系，论证了锡矿山超大型锑矿的地幔交代流体成因，并以此为基础提出盲矿体地质找矿标志：即指示地幔交代流体活动的构造，尤其是具有成矿元素和碱质异常、热液蚀变的断裂构造；有利的岩石物理化学性质；硅化、碳酸盐化围岩蚀变等。

In this dissertation, sedimentology, historical geology, structural geology, geophysics, structural dynamics/geometric, plate structure etc were combined properly. Taking Jiyang depression as studying object, fault distribution of different periods was analyzed, and thus discussing their structural dynamics. Using tectonic subsidence history modeling and denudating relationship between hanging wall and foot wall in Mesozoic faults, fault activity characteristics were discussed.
