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；玄武巖漿的起源深度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。These interactions may also serve as important ways for lithosphere recycling and mass exchange between the shallow and deep parts of the earth, which could significantly affect deep mantle convection and surface tectonic processes
這種相互作用被認為是穩定克拉通巖石圈遭受改造甚至破壞的深部機制，同時還是地球深、淺部物質交換的重要方式，因而顯著影響著地球深部的對流和地表的構造過程。Integrated with other late paleoproterozoic granitoids within the central tectonic zone, it indicates that there was a tectonic transitional process from extension to compression during late paleroproterozoic in the southern segment of the central zone of ncc
巖石學和地球化學研究表明王家會花崗巖屬於後碰撞花崗巖，結合區域上古元古代地質特徵，表明華北克拉通中部帶南段古元古代晚期的花崗巖構成了與正常造山過程花崗巖漿演化相反的序列。The potential presence of a further 100bn barrels in the western desert highlights the opportunity for iraq to be one of the world ' s biggest oil suppliers, and its attractions for international oil companies - if the conflict in the country can be resolved
西部沙漠地區的儲量可能比原先的預期高出1000億桶，顯示伊拉克有可能成為全球最大的石油供應國之一，也顯示出它對國際石油公司的吸引力- -但前提是，該國的沖突問題能夠得到解決。The largest diamond found on earth was the 3, 106 - carat cullinan
地球上發現的最大鉆石是重3106克拉的克利蘭鉆石。That would put iraq in the top five oil - producing countries in the world, at current rates
