- 4 . the feature of linearity and ring structures shows that three structural lenses that are formed by the junction of four level i faults in alignment are helpful to the formation of ore - body . in longshujiao and longtouzhai lenes there are many intersectant east - north and west - north low level faults , so they are concentration place of ore - bodys
4 、从遥感线环构造特征上看，区内的四条主要东西向线性构造，是级控岩控矿线性构造，它们在走向上弧形交接形成三个构造透镜体，是成矿的有利部位。 - The basin - formed mechanism , evolution model and petroliferous geological features of compresso - shear basins in the world are analyzed , by which six aspects of the features are summarized as follows : 1 ) in the compresso - shear process , the sedimentary speed of basin is high , forming thicker coarse - grained clastic rocks which normally shape good petroleum reservoir ; 2 ) the source rocks of basin tend to coming from the organic matter - enriched rocks formed in pre - compresso - shear stages , except that in intense compresso - shear process , deep water - semi deep water source rocks are possibly developed in pre - compresso - shear stages , e4xcept that in intense compresso - shear process , deep water - semi deep water source rocks are possibly developed in frontal of deep depression ( fore deep ) of thrust belt ; 3 ) the en echelon folds ( including anticline and fault - nose structure ) are generally as good oil traps ; 4 ) the compresso - shear process is helpful to hydrocarbon accumulation ; 5 ) it may promote the maturity and hydrocarbon - generating process of organic matte , and 6 ) the thrust belts in the surrounding areas of compresso - shear basin are favorable are favorable domains for petroleum concentration
摘要通过对世界上压扭性盆地的成盆机制、演化模式和油气地质特点分析，总结压扭性盆地具有6个方面的石油地质特征：压扭作用期间盆地的沉积速率较高，一般形成较厚的粗碎屑沉积，它们常构成很好的油气储集层：盆地的烃源岩往住来自于前压扭期砂成的富含有机质的岩石，但在强烈的压扭作用期间，在冲断带的前缘深坳陷（前渊）中有可能发育深水半深水相的烃源岩；压扭（张扭）作用期间形成的雁行式褶皱（包括背斜和断鼻等）往住是很好的油气圈闭；压扭作用易于成藏；压扭作用可以促进有机质的成熟生烃作用；压扭性盆地的周边冲断带是油气赋存的有利部位。 - The author suggests that the three lithosphere - scale faults , lancangjiang fault , jinshanjiang - ailaoshan fault and axis fault in the middle of the basin , are the main geological structures that control the formation of basin , magmatism and metallogenic congregate district . the anticline structure with an axis of triassic strata and the related fault system within the basin , and gonglang arch - shaped folding structure in the south of the basin are the geological structure controlling the formation of ore fields . junctions of two or more faults with different orientation , interlayer cataclastic structural zone and oxidation - reduction ( redox ) boundary were the favorable position for the formation of ore bodies
认为澜沧江断裂、金沙江-哀牢山断裂及盆地中轴断裂这三条岩石圈断裂是主要的控盆-控岩(岩浆岩)构造及矿集区尺度的控矿构造；盆地中以三叠系为轴的背斜构造及相关的断裂系统、盆地西南缘公郎弧形构造等是矿田尺度的控矿构造；多组断裂的交叉、层间破碎带及地层柱中的氧化还原界面是形成矿体的有利部位。 - Throughout researching it has been found that three main types of copper deposits , which mafic - ultramafic rock , marine volcanic rock and porphyry , with middle proterozoic , paleozoic and mesozoic in gansu , china . the cu - bearing formation , deep major faults and late structural - magmatic zones formed in specific geotectonic setting are main ore - controlling and metallogenic factors for copper , gold and polymetallic minerals in this area , and their convergent positions are effective ones formed ore bodies in space
通过研究认为：镁铁质-超镁铁质岩型、海相火山岩型及斑岩型三种铜矿类型，是甘肃的主要铜成矿类型，其主成矿阶段为中元古代、古生代以及中生代；特定大地构造背景下形成的含矿建造、区域性深大断裂以及后期斜向构造-岩浆活动带，是该区铜、金及多金属成矿的主要控矿因素，三者在空间上的复合是矿床体形成的有利部位。
