辽东湾盆地古近系沙河街组产有一套分布仅限于深凹陷内的深湖相白云岩，岩性主要为泥-微晶白云岩，物质组分以铁白云石为主，在深湖相暗色泥岩中呈很薄的夹层产出，累计厚度6~10 m，产出位置明显受区域内辽中凹陷西界的北北东向基底断裂控制。

The leucogranites veins occurred widespreadly in the para-metamorphic rocks, in which the hypersthene melagranulite distributed. That suggests the source rocks of leucogranites of the High Himalaya are para-metamorphic rocks. For the basement was uplifting, pressure relieved and lacked water, source rocks were melting partly and formed the leucogranite magma.

基底副变质岩中广泛分布淡色花岗岩脉体，在基底副变质岩中的淡色花岗岩脉体中发现紫苏辉石暗色麻粒岩残留体，这表明本区高喜马拉雅淡色花岗岩源岩为基底副变质岩，且基底副变质岩是在基底快速隆升降压的条件下发生缺水熔融生成的淡色花岗岩岩浆。

The Huashan—Guposhan granitoid belt consists of Tong'an, Huashan, Niumiao, Jinziling, Wuyangshan, Lisong and Guposhan granitoid bodies. Petrographycally, they are diorite, quartz monzonite, monzonitic granite and syenogranite. Dark mafic enclaves are very common. Their major emplacement ages are 160～163 Ma.

花山-姑婆山花岗质杂岩带由同安、花山、牛庙、金子岭、乌羊山、里松和姑婆山等岩体所组成，岩性为闪长岩、石英二长岩、二长花岗岩和正长花岗岩等，富含中基性暗色包体，主要侵位时代为160～163 Ma。

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。

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。

The dark dikes associated with mineralization in the Jinchanggouliang mine area,are mostly fine diorite-quartz diorites and diorite porphyrite-dacite porphyries.

金厂沟梁金矿区中与成矿伴生的暗色脉岩主要是细晶闪长岩石英闪长岩、闪长玢岩英安斑岩类。

Dark mudstones were developed in the maximum lake flooding period of Chang 7,which are the main source rocks.

延长组长7段最大湖泛期发育一套暗色泥岩，干酪根类型为腐植-腐泥型，是盆地主要生油岩。

Among three sets of hydrocarbon Source rock in this basin, the dark-coloured mudstones in Nantun formation and Damoguai-He formation developed best and distributed widely, they even distributed in whole of the area.

海拉尔盆地的三套烃源岩，以南屯组和大磨拐河组暗色泥岩最为发育，且分布范围广，在全区均有分布，而铜钵庙组仅发育在嵯岗隆起两侧埋深大的凹陷内。

The characteristics of sequence development, source reservoir - seal assemblage and types of hydrocarbon reservoir for each sequence were discussed in detail. The dark colored shale of deep lacustrine facies in the transgressive system tract of SⅡ sequence deposited around the maximum flooding surface is the main source rock in this area. The shale of shallow lacustrine facies in the TST of SⅢ sequence around the MFS is the most important regional seal rock.

结果表明，该区古近系可划分为SⅠ，SⅡ，SⅢ和SⅣ4个层序，分别对应于房身泡组、沙三段、沙一段沙二段和东营组。SⅡ层序水进体系域最大湖泛期沉积的半深湖深湖相暗色泥岩是研究区的主力烃源岩系；SⅢ层序水进体系域最大湖泛面附近的浅湖相泥岩是最重要的区域盖层。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
