縫合帶盆地
英文
sutural basin-
The coqen basin in xizang lies between the bangong - nujiang suture zone and yarlung zangbo suture zone, and once extended northwards and southwards, respectively centred by the qiekan - goicang - asog rift zone as the center of deposition and subsidence during the middle jurassic to the early creatceous. ( 1 ) during the middle - late jurassic, the rift zone was occupied by deep - water turbidites, radiolarian siliceous rocks, shallow - water carbonate rocks, clastic rocks and basic - ultrabasic rocks, while both sides of it by littoral and shallow marine elastic rocks and carbonate rocks
摘要位於班公湖怒江縫合帶與雅魯藏布江縫合帶之間的措勤盆地，在中侏羅世早白堊世期間具有以且坎古昌阿索裂谷帶為沉積、沉降中心向南北兩側展開的古地理格局：中晚侏羅世時期，裂谷帶內由深水濁積巖、放射蟲硅質巖和淺水碳酸鹽巖、碎屑巖巖片及基性超基性巖等組成；裂谷帶兩側由濱淺海相碎屑巖和碳酸鹽巖組成。According to the characteristics of strata, tectonization and magmatism within the research area in the southwest margin of north china paleocontinent, and under the ideological guidance of mobilism and systematology, the geotectonic framework of the area could be divided as follows : ( 1 ) the longshoushan mountains continental margin ; ( 2 ) the hexi corridor back - arc basin ; ( 3 ) the northern qilianshan mountains suture zone ; ( 4 ) the central qilianshan mountains dispersion type island arc terrane ; ( 5 ) the southern qilianshan mountains back - arc basin ; ( 6 ) the qaidam massif
根據本區地層、構造、巖漿作用特點，在「系統論」 、 「活動論」思想指導下，釐定華北古大陸西南邊緣的構造格局如下：龍首山陸緣帶、河西走廊弧后盆地、北祁連縫合帶、中祁連離散型島弧地體、南祁連弧后盆地、柴達木地塊。After synthetic evaluation to the permian reservoir, it was considered that there were deep lake facie in mazhong - heidun - shibandun structure zone, it was suitable to depositing thick carbonate rock. these cracks were developed in the zones where the stress was concentrated. these zones are fairly good oil and gas exploration areas.
對三塘湖盆地二疊系儲層進行綜合評價后，認為：該區馬中?黑墩?石板墩一帶屬半深湖沉積亞相，有利於碳酸鹽巖的沉積，儲集體沉積比較厚，並且此帶屬于應力集中的變形強烈帶，故裂縫較發育，從而成為最有利油氣勘探區，其次有利區為牛圈湖構造帶，這主要是由牛圈湖地區的顆粒溶孔較發育所致。Based on the geological, stratigraphic and geochemical characteristics of the ophiolitic melange, island - arc and rift volcanic rocks from the jinshajiang zone, an archipelagic tectonic model with multi - rift and multi - subduction is proposed to explain the evolution of jinshajiang paleo - tethys. the ophiolitic melanges of the jinshajiang zone are mainly outcropped at baimangxueshan, tongduo, gongka, dongzhulin and jiyidu in the deqin county. the geochemistry of major and trace elements of the jinshajiang ophiolite shows its geochemical characteristics are similar to those of the more and island - arc volcanic rocks, but different from those of the typical n - mopjb
金沙江蛇綠混雜巖主要分佈在德欽縣的白茫雪山、通多、共卡、東竹林和吉義獨地區，主量和微量元素地球化學特徵研究表明，金沙江蛇綠巖不具有典型n - morb的地球化學特徵，而具有介於morb和島弧之間的地球化學特徵，暗示它並非形成於寬闊的大洋環境，不是古特提斯在滇西北地區的主縫合帶，可能是古特提斯多島洋體系中的一個弧后盆地。分享友人
