  1. 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,得出如下論:本區上地幔的物質成有尖石二輝橄欖、二輝、單斜輝石、純橄欖、方輝橄欖、石榴石二輝橄欖、金雲母二輝橄欖、榴輝;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 ;從幔源砂礦物的溫壓估算果,可以推斷出石圈厚度可達204 . 9km ;綜合石圈物質成特徵、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。
  2. Because of the absence of mantle xenoliths and xenocrysts, it is the first time that this paper looks on the native heavy minerals deriving from mantle, which were collected at the terraces of the two rivers, kalakshi river and yulongkashi river, as objects and takes into account the geochemical characteristics of the rocks deriving from mantle such as keliyang lamproite and so on to study the composition of lithospheric mantle, the characterics of palaeozoic era lithospheric mantle, mantle thermal state, and diamond metallogentic mantle geological conditions in research field

    為達到研究目的,本文首次以喀拉喀什河和玉龍喀什河沿岸階地的幔源砂礦物(單斜輝石、鉻尖石類礦物、鈦鐵礦以及石榴石)為研究對象,合鉀鎂煌斑等區內已發現的幔源石及其中地幔物質對該區地幔物質的成、古生代石圈地幔特徵、石圈熱狀態以及該區金剛石成礦地幔地質條件做了嘗試性的研究工作。
  3. Santanghu basin, located in the edge of the southern siberian plate, has the double basements of the pre - cambrian crystalline basement and the palezoic metamorphic basement of volcanic - sedimentary rocks

    三塘湖盆地位於西伯利亞板塊南緣,具有前寒武紀基底和古生代火山-碎屑褶皺基底成的雙基底。
