  6. 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。
  7. The geochemical data of the benzilan and pantiange volcanic rocks from the jinshajiang zone yielded characteristics similar to those of island - arc volcanic rocks : intensive enrichment in lile and different depletion in hfse, nb, ta, ti, p and zr, hf. their lower e nd ( t ) values ( - 4. 03 - - 11. 29 ) indicate that they are derived from an emu mantle source or a mixing source between dm and emu respectively, but which are affected violently by subduction materials

    同位素研究顯示，它們具有較低的_ （ nd ） （ t ）值（ - 4 . 03 - 11 . 29 ） ，表明它們分別來源於富集地幔emii以及虧損地幔dm和emii兩元混合的源區，兩地的火山巖源區都受到了俯沖帶物質的強烈影響。
