By means of kiba formation , k . ibt " and kibt2 segments analysis on the equivalent time stratigraphic framework , subtle traps will be predicted on stratigraphic traps and lithological traps . the results from the research indicated that : ( 1 ) this paper further indicates the control significance of southern boundary fault displacement component , which downthrown side forms syncline or anticline , and points out that 4 anticlines in south are adjustment zone and are the entering lake position of ancient river 本论文的主要认识和结论如下: ( 1 )进一步认识南缘边界断层位移量对下降盘形成次凹或横向突起的控制意义,认出南缘的4个突起是调节带之所在,也是古河流入湖处。这种格局导致凹陷强烈分割,并以横向搬运为主。
The hanging wall of sag extended in southeast direction , with the tulage fault being the boundary fault . yinggete - bagemaode metamorphic core complex developed adjacent to northwest of chagan sag , which evolved from late jurassic to cretaceous with three - layer construction style . the kinematics mechanism of metamorphic core complex and chagan sag is a simple shear model , chagan sag extended and faulted as the metamorphic core complex rised 在查干凹陷西北侧发育英格特?巴格毛德变质核杂岩带,可能具有三层结构模式,其形成与演化时代为晚侏罗世末?白垩纪;该变质核杂岩与查干凹陷的运动学机制为统一的简单剪切模式;在变质核杂岩隆升的同时,查干凹陷发生伸展断陷。
Bachu arch is a large back - thrust uplift . tectonic evolution of its large boundary fault fracture have relation with oil / gas distribution involuntarily . its large boundary fault fracture is basement rift formed in late hercynian period and strongly actived in late himalayan period . oil / gas distribution of bachu - markit have relation with fault interspace distribution . so , this paper also discussed interspace distribution and movement stage of fault 巴楚隆起是一个大型背冲断隆,其边界大断裂的形成演化自然关系到本区的油气分布,隆起的边界大断裂多是海西晚期形成的基底断裂,后在喜山期强烈活动,兼具压扭走滑性质。
