Kubusunan granite is chracterized by low87Sr/86Sr initial values and high ε values, indicating its origin partly from mantle rocks. The number of microgranular dioritic enclaves is the direct evidence for crust-mantle magma mixing, thus showing that enclaves are the residual formed from the partly fusing of basic magma.
库布苏南花岗闪长岩体具有低锶初始比值I和正ε值,表明花岗岩的来源有地幔物质参与,而大量发育的暗色微粒闪长质包体是壳幔岩浆混合作用最直接的证据,微粒包体是基性源岩部分熔融作用形成的残余体。

On the basis of the information obtained through field geological survey and indoor integrated petrological and petrochemical studies, it has been found that there is a clear and sharp pulsatory intrusive contact between various rock units of the rock body and a number of dark dioritic microinclusions are present. The rocks are characterized by a relatively low total REE content, relative enrichment in K, Rb, Ba and Th and relative depletion in Cr, Ti, Nb, Sr and P.
根据野外地质调查资料和室内的岩石学、岩石化学等特征的综合研究成果,发现该岩体各单元之间呈脉动式侵入接触,接触界线清晰,且含有较多暗色闪长质微粒包体;稀土总量较低,K、Rb、Ba、Th元素相对富集,Cr、Ti、Nb、 Sr、Zr、P元素相对亏损。

Several points can be concluded for the area from this paper study:(1) Hydrocarbon mainly occurs in the lower interval of bioclastic limestone and dolomitic limestone(the special lithologic interval ) in Es_1 Member,in which solution pores well developed;(2) Traps are mainly anticlines controlled by f.
本文研究表明,大中旺地区油气主要分布在沙一段下部的生物碎屑灰岩和云质灰岩段,储层溶蚀孔隙发育;圈闭主要为受断层控制的断背斜构造;原油具有高密度、高粘度、中低凝固点、高初馏点、高含硫量和高胶质沥青质等特点,属于未成熟—低成熟油;油源为本地咸水环境下形成的沙一段暗色泥岩。

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。
