  2. Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits

    最後,綜合本區幔源礦物和地幔石的特徵以及地球物理資料,得出如下結論:本區上地幔的物質組成有尖晶石二、二、單斜、純方輝橄欖巖、石榴石二、金雲母二、榴;與中國東部以及華北地臺上地幔相比,研究區上地幔具有富集主元素中相容元素和虧損其中的不相容元素的特徵,局部熔融程度較高;上地幔存在橫向和縱向的不均一性,從西部的克里陽到喀拉喀什河和玉龍喀什河流域, al和lree富集程度呈下降趨勢,不同來源的相同礦物中主元素的含量差異較大;地質歷史時期這里可能發生過地殼俯沖並產生殼幔混合作用;玄武漿的起源深度73km ;從幔源重砂礦物的溫壓估算結果,可以推斷出石圈厚度可達204 . 9km ;綜合石圈物質組成特徵、石圈熱狀態、地幔溫壓狀態、氧逸度以及幔源石和幔源礦物的化學成分,認為研究區具備了金剛石成礦地幔地質條件。
  3. Ultramafic rock fragments, which almost is altered to ophite, distributed in structural zone and displayed structural lens. so far, 9 fragments were discovered and mapped in nujinshan and bujing area ultramafic rock can be divided two kinds according to it ' s geochemical characteristics. one can be correlated with metaperidotite, which represented residual part that primary pyrolite underwent moderate partial melting, from some representative ophiolite melange in the world

    按超鎂鐵類的地球化學特徵可將其劃分為兩類:一類具有較高而穩定的mgo 、較低的al _ 2o _ 3 、極低的cao , m f值為8 . 0 ? 8 . 4 ,按標準礦物組合進行分類可定為方輝橄欖巖,且均為fa _ ( 100 ) 、 en _ ( 100 )的鎂質端元組分;可與世界上一些典型的蛇綠套中變質進行對比,代表了原始地幔中等部分熔融作用后殘余物。
