ophiolitic melange 中文意思是什麼
-
The geochemical characteristics of gabbros from the jinshajiang ophiolitic melange indicate that they were derived from a mantle source different from that of volcanic rocks, which may be a product in the ocean rift in the earlier stage
東竹林蛇綠混雜巖中輝長巖地球化學特徵表明，它與火山巖不同源，可能是洋盆裂谷初期的產物。 -
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。 -
Thus, they might be derived from a back - arc basin with an archipelagic system in paleo - tethys, instead of a large ocean basin. the isotopic geochemistry shows that the jinshajiang ophiolitic melange has higher e nd ( t ) values ( + 7. 42 - + 5. 44 ), suggesting that it may be derived from a lree depleted mantle source without significant contamination by the continental crust, but affected slightly by a fluid from a subducted ocean crust
同位素地球化學研究表明，金沙江蛇綠混雜巖具有較高的_ （ nd ） （ t ）值（ + 7 . 42 + 5 . 44 ）暗示蛇綠巖來源於lree長期較虧損的地幔源，演化過程中沒有受到陸源物質的明顯混染，而主要受到少量俯沖洋殼析出流體的影響。 -
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。 -
In the light of rock association, origin, age, deformation and metamorphism, disintegration and collage, migration and displacement, the " litang ophiolite group " is redefined as the " litang ophiolitic melange group ", which may be redivided into two formation complexes, i. e. the kar ophiolite formation and waneng ophiolite formation and five types of exotic blocks composed of clastics and marbles
按結合帶內巖塊的不同組分、不同來源、不同時代、不同變形變質程度的不同，對各類巖塊進行四維裂解拼合復原后劃分為兩個巖組（卡爾蛇綠巖組、瓦能蛇綠巖組）及碎屑巖、大理巖等組成的5類外來巖塊。
