    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。
  3. This important tectonic zone parallel to the isotopic geochemical steep zone, which represented a suture line between the yangtze and cathaysian blocks. the geochemical evidence of the jianshui volcanic rocks from the sw part of shizong - mile zone shows that their lithologic types are tholeiites with the comparative flat ree patterns and enrichment in th, depletion slightly in nb, ta, and flat hfse. thus, they may be formed in a back - arc basin with the characteristics between morb and island - a

    該構造帶西南段的建水火山巖地球化學特徵研究表明，該火山巖為拉斑玄武巖，具有較平坦的稀土分配型式， th較富集， nb 、 ta輕微虧損，高場強元素分佈較平坦，具有介於島弧和morb之間的地球化學特徵，可能形成於弧后盆地環境。
  4. It is presented that the hydrous fluxing as well as adiaba tic decompression plays an important role in melting of morb - like mantle beneath marina trough. compared with basalts from other back arc basins, it concludes that the magma varies from morb - like to arc - like with the evolution ; during the earlier stage of evolution, there coexist the two morb - like and arc - like lavas, it may be the nature of the magma in back arc basins ( especially in the earlier stage )

    綜合馬里亞納海槽和其他弧后盆地玄武巖的研究成果發現，弧后盆地特別是早期擴張的弧后盆地，其巖漿產物均具從似島弧型到似洋中脊型玄武巖的時空演化特徵；同時存在島弧型和morb型兩種熔巖，可能是弧后盆地（特別是早期擴張弧后盆地）巖漿作用的一個共同屬性。
  5. The high - pressured granulites are formed both in the convergent area such as the subduction zones and collision zones and in the spreading area such as the bottom of the island arcs

    高壓麻粒巖既可形成於匯聚型構造環境如俯沖帶、碰撞帶等，也可形成於伸展型構造環境如島弧底部。
  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. It is very resembly representative island arc volcanic rock in the geochemistry character, so i demonstrate that a petrofabric formed tectonic activity section and island arc environment ; i also demonstrate that parametamorphite in the a petrofabric formed tectonic activity section. b petrofabric is very resembly a petrofabric in many aspects, so i think that b petrofabric also formed island arc environment, but volcanic activity obvious weakened in the b petrofabric stage. c petrofabric formed carbonatite mesa

    在地球化學特徵方面與典型島弧火山巖非常相似，得出a巖組形成於構造活動區，形成環境為島弧環境。 a巖組的副變質巖的原巖碎屑巖是快速堆積的，處于構造活動區。 b巖組和a巖組對應的巖石在各個方面都非常相似，所以形成環境也為島弧環境，只是火山活動在這期間明顯減弱。
  8. Chemical characteristics of atmospheric dust in lanzhou
