摘要依舒地堑位于黑龙江省东部，为新生代断陷盆地，汤原断陷和方正断陷为其两个面积较大的二级构造单元。 - Based on an integrated analysis of the surface geological , aeromagnetic , gravity , mt and seismic data from the area of mangnai to serteng mountains in the western qaidam basin , the authors think that the qaidam basin is sandwiched between the north kunlun block and serteng tectonic belt , including two first - order tectonic units the qaidam block and the southern margin of the qilian block and four second - order tectonic units the northern margin of the north kunlun block , qaidam basin , serteng tectonic belt and suhai lake basin in the south of the qilian block
摘要通过柴达木盆地西部茫崖赛什腾山地表地质、航磁、重力、大地电磁测深和地震资料的综合分析，认为柴达木盆地夹持在昆北地块与赛什腾构造带之间，其中包括柴达木地块与祁连地块南缘2个一级构造单元和昆北地体北缘，柴达木盆地，赛什腾构造带和祁连地块南部的苏干湖盆地等4个二级构造单元。 - In summary , we constructed a structure framework on the eastern district of the nanpanjiang depression , made a new structure regionalism , confirmed that the border of nanpanjiang depression was nandan - du ' an fault and xialei - lingma fault , and analyzed the structural characteristics of secondary structure units in detail
在上述研究的基础上，对南盘江坳陷东部地区进行了构造格架的建立和构造区划，确定了南盘江坳陷的东部边界为南丹-都安断裂带，南部边界为下雷-灵马断裂带；并对二级构造单元的特征进行了分析。 - During this evolution , seven second - order tectonic units were formed ; from north to south are the mingqianri cretaceous residual sea basin , the arsuo tectonic melange zone , the taricuo - wenbu yenshan magmatic arc belt , the cuoqin - bangduo late paleozoic composite back - arc basin , the jiangrang - geerdi faulted uplift , the gangdise - chazi himalayan magmatic arc belt , and the xigaze - anba fore - arc basin . these units comprise important parts of a poly - arc - basin system and exhibit evolutional features of mesozoic to cenozoic arc - basin systems . mosaic pattern of these tectonic units delineates the lithosphere coupling processes of the gangdise tectonic belt under mechanisms such as back - arc basin attenuation and arc - continent collision
自中新生代以来，冈底斯构造带经历了洋壳俯冲、弧陆碰撞、陆内俯冲-碰撞、走滑和块段隆升的多阶段构造演化历程，形成了由北向南七个二级构造单元，即岷千日白垩纪残余海盆、阿索构造混杂岩带、它日错?文部燕山期岩浆弧带、措勤?帮多晚古生代复合弧后盆地、江让?格尔耿断隆、冈底斯?查孜喜马拉雅期岩浆弧带、日喀则?安巴弧前盆地。
