  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,綜合本區幔源物和地幔巖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輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲母二輝橄欖巖、榴輝巖;與中國東部以及華北地臺上地幔相比,研究區上地幔具有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程度呈下降趨勢,不同來源的相同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;玄武巖漿的起源深度73km ;從幔源重物的溫壓估算結果,可以推斷出巖石圈厚度可達204 . 9km ;綜合巖石圈物質組成特徵、巖石圈熱狀態、地幔溫壓狀態、氧逸度以及幔源巖石和幔源物的化學成分,認為研究區具備了金剛石成地幔地質條件。
  2. On the basis of previous research works, new exploration wells, new appraisal wells and 3d seismic material are added to new research work in which rock and mineral, sedimentary facies and oil bearing characters are studied deeply by employing the methods of petroleum geology, sedimentary geology and reservoir geology. the results of reservoir prediction on fluvial sandbody in the upper of formation of guantao group obtained by using coherent analysis and acoustical impedance inversion bring good effect to the exploration and development of chengdao oilfield

    本文在以往工的基礎上,補充新鉆探井、評價井和三維地震資料,運石油地質學、沉積地質學、儲層地質學等原理方法,對埕島油田主力含油層系館上段地層的巖、沉積相及油氣特徵進行了深入的研究,對館上段河流相體進行了以測井約束地震反演為主的儲層預測研究,研究成果為繼續開展埕島油田的勘探開發提供了重要依據。
  3. According to the analysis on the lithogeochemical features and the carbon and oxygen isotopes of calcareous sandstones, it is realized that there some genetic relation between the formation of calcareous sandstone and uranium mineralization in the oxidation - deoxidation transitional belt, that is the precipitation and enrichment of uranium is accompanied by the deposition of carbonate and formation of calcareous sandstone

    根據鈣質巖的巖石地球化學特徵,結合碳、氧同位素分析認為,氧化還原過渡帶中鈣質巖的發育與鈾化的形成具有一定的成因聯系,即在鈾沉澱的同時,伴隨著碳酸鹽的析出,形成鈣質巖。
  4.
