Based on the analysis of distribution of upper jurassic and lower cretaceous strata and basin - controlled faults , tanlu fault zone strike slip to develop the three nw - trending grabens from north to south western to tanlu fault zone in late jurassic and early cretaceous , which are bohai graben , jiyang graben and luxinan graben . based on the analysis of regional geology , the basic tectonic pattern of bohai basin is the cenozoic basin pattern since early paleogene . the outline , structure , deposit characteristics and heat flow distributions show that the basin is pull - apart basin in cenozoic time . the tectonic evolution pattern can be reconstructed based on the analysis of cenozoic strata , deposit thickness , location and activity of basin - controlled faults in the different depresses in bohai basin . the characteristics of structure and depositment in this mesozoic and cenozoic time show that bohai basin is a mesozoic and cenozoic composite basin 根据中生界上侏罗统和下白垩统地层和控盆断裂分布分析，中生代晚期晚侏罗早白垩世郯庐断裂带的左旋走滑平移导致郯庐断裂带以西自北向南发育了3个北西向断堑系，即北部的渤海断堑系中部的济阳断堑系和南部的鲁西南断堑系。从区域资料综合分析，渤海湾盆地的基本格局是早第三纪以来的新生代盆地格局。渤海湾盆地的形态构造和沉积特征及热流值分布表明该盆地在新生代为拉分盆地。
Geological , geophysical and geochemical research indicate that ore deposits space distribution present belt in nw direction and strip in ne direction is controlled by the lengthwise structure and transversal structure . in the fold - thrust belt , those ore deposits formed in pre - intracontinental - orogenic stage , such as dingqinnong ag - cu polymetal ore deposit , have the character of one orebody beneath one , so it is optimistic to search new orebodys in deep 地质、地球物理、地球化学研究表明江达构造带矿床在空间上呈现北西成带、北东成条规律分布受纵向构造与横向构造的双重控制；在褶皱?冲断带，陆内造山期之前形成的矿床(如丁钦弄银铜多金属矿床) ，常出现矿体多层叠置、矿下有矿的现象，深部找矿前景乐观。
Through the correlation of nww - see and sn , the thickness and limestone intervals of matuo formation gradually increase from west to east . this represent the center of sedimentation is possible located in east of the region . the matuo formation thickness gradually increase and then reduce from north to south 通过北西西?南东尔向和南北向剖面对比，玛托组地层横向变化表现为由西往东，玛托组地层厚度逐渐加大，灰岩夹层也增多，反映当时沉积中心在研究区东部，而由北往南，厚度先逐渐增大，后减小，灰岩夹层增多，由北往南的古地理格架为滨面?碳酸盐台地?斜坡环境。
Nw compressive structures are developed in indosinian epoch in which folds are predominant and companied with some small thrusts . nearly ns or nnw compressive structures are developed at the end of yanshan epoch in which it is mainly overthrusted structures and closed folded structures . large gentle anticlines and synclines are developed from the end of mesozoic to early tertiary , and antithetic sagging structures are developed in mesozoic 研究发现，本区印支期发育了以褶皱为主、局部伴有小型逆断层的北西向压性构造，燕山末期(中生代末期)发育了以逆掩构造和紧闭的褶皱构造为主的近南北向或北北西向压性构造，中生代末到第三纪早期发育了以宽缓为特征的大型背斜向斜构造，以及中生界内部的逆牵引构造。
Those two phases of conjugated shear joints are differ from each other in spatial distribution , which is a reflection of the spatial evolution of the fault zone . it can beinferredfrom the information about macrostructure , superimposed deformation of tectonites , paleotectonic stress field of joints and other related documents that there had been three stages of significant activity since zijingguan fault zone was activated . the first stage was about from middle juiassic to early cretaceous , when the fault zone activated left - laterally under nw - se striking transpression 宏观构造组合特征、构造岩变形叠加信息、节理的古构造应力场信息及前人区域资料表明，紫荆关断裂带自古生代末开始活化以来有三次主要构造活动：第一次是中侏罗世?早白垩世，在北西?南东向近水平挤压作用下，断裂左行压扭性活动，控制太行山地区岩浆岩带及与其相关的接触交代型矿床的形成。
Tertiary structures are developed in mesozoic - palaeozoic tectonic settings , the general framework is faulted depression faulted in the north and onlapped on the south and arch bounded by faults . they are controlled and affected by three sets of large successive - active faults ( nw , ne and nee strike ) , they are successive and segmented , with multiples types and zoning distribution 第三系的构造是在中、古生界构造的背景上发育起来的，它以北断南超的箕状断陷和断层为界的凸起为总的构造格架，受北西、北东和北东东向三组继承性活动大断层的控制和影响，构造具有继承性和分割性、类型具有多样性、分布具有分层分带性。
The elevation of the city is 1891 metres above sea level . kunming is surrounded on three sides , leaving one side facing the dianchi lake to its south . the panlongjiang river , a tributary of the yangtze river , winds through the city . the magic combination of various geographical factors makes kunming a " spring city " and a " flower capital " without bitter cold in winter and scalding heat in summer 昆明位于云贵高原中部，地理位置为东经120度45分北纬25度2分海拔1891米，东北西三面环山，南濒“高原明珠”一滇池，长江水系的盘江穿城而过种种地理因素的神奇组合，使其得以成为世界上少有的“夏无酷暑冬无严寒”的“春城” “花都” 。
Through the all - sided tectonic analyses , it can be deduced that there are two aspects will be the hidden defects to the dam and the engineering stability of the reservoir area . one is the dislocation interfaces resulting from the the majiaheba faultage ' s thrusting overriding and other causes of formation . the second is the region of strong deformation , such as the above of the dam , middle and high positions of the lava layers and the regions of overprint of the structure of ne to the one of nw , which should be taken into account especially 通过区域和坝区错动带的全面构造解析，认为由马家河坝断层逆冲推覆作用而在坝区形成的向金沙江下游缓倾的错动带以及其它成因的错动带是坝区和库区工程稳定的隐患，尤其是变形较强的坝址区上游区、中高层位以及北西向构造期的错动带叠加于北东向构造期错动带的部位，更应该引起足够的重视。
In north of whole three rivers tectonic belt include jiangda tectonic belt , regional geochemical research indicate that its geochemical anomaly present the character of belt in nw direction and trip in ne direction , too . this is the geochemical response in earth ' s surface of deep - action . in nature , it is the consequence resulted by the terranes inserted as strips and blocks , regional transversal structure develope 区域地球化学研究表明，包括江达构造带在内的三江构造带北段，区域地球化学异常亦表现出北西成带、北东成条特征，这是深部作用的地表地球化学响应，实质上是地体条块镶嵌、区域横向构造发育以及与此相关的壳幔长期作用的结果。
On the base of the study on the hydrogeochemistry at dam area , the author analyzes the last hydrochemistry data of bearing crevice water . from the diagram of piper and the correlation diagram of na / ca and na , it is known that the deep bearing tectonic fracture water is produced by two sources mix , meanwhile it is found out that there is better hydraulic power connection among bore d46 , d503 , d211 , which shows there is better nnw hydraulic power connection at complex zone making up of fault no . 7 , no . 15 and no . 2 在坝区的水文地球化学的研究基础上，整理分析了坝区以前的承压裂隙水的水化学资料，从piper图、 na ca ? na关系图，说明了坝区深部承压裂隙水是二源混合的产物，结合聚类分析表明了坝区d46 、 d503 、 d211钻孔之间存在较好水力联系，进而说明了在坝区f7与f15断裂带以及f2构成的复杂地带存在北北西向较好的水力联系。
