tectonic melange 中文意思是什麼
tectonic melange
解釋
構造混雜巖-
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
自中新生代以來，岡底斯構造帶經歷了洋殼俯沖、弧陸碰撞、陸內俯沖-碰撞、走滑和塊段隆升的多階段構造演化歷程，形成了由北向南七個二級構造單元，即岷千日白堊紀殘余海盆、阿索構造混雜巖帶、它日錯?文部燕山期巖漿弧帶、措勤?幫多晚古生代復合弧后盆地、江讓?格爾耿斷隆、岡底斯?查孜喜馬拉雅期巖漿弧帶、日喀則?安巴弧前盆地。 -
The basic to ultra - basic rocks are distributed along suture zones, whereas the intermediate to acidic intrusives occur mainly to the south and north of the arsuo tectonic melange zone and the angren ophiolitic melange zone
基性-超基性巖沿結合帶分佈，而中酸性侵入巖主要分佈在阿索蛇綠混雜巖和昂仁蛇綠混雜巖的南北兩側。 -
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。 -
The geological, geochemical and geochronological features regarding to this ophiolite melange and related blocks to its both north and south sides have been investigated in this thesis. as a consequence of this research the tectonic evolution process of western kunlun mountain has been discussed. the qimanyuter ophiolite melange takes role as a tectonic boundary separating south kunlun massif from north kunlun massif.
本論文工作對該蛇綠混雜巖帶的地質特徵、巖石地球化學特徵、主要巖石單元的年代學，以及被它所分開的南北兩側地塊的地質、地球化學特徵，初步恢復和探討了早古生代時期西昆侖造山帶的構造演化過程。 -
