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。Strong negative 8 eu shows the granites are high evolved granite. ( 6 ) the tetrad effect of ree and the obvious fractionation between k - rb, y - ho, zr - hf, nb - ta, and sr - eu in the dajishan granites indicate that, the aqueous fluid pays an important role in the evolution of the granites, as well as indicate that there exist enough interaction between peraluminous melt and aqueous magmatic fluid. furthermore the fluorine played a very important role in this process
( 6 )大吉山花崗巖類稀士元素具有「四重效應」配分的特點以及微量元素對kjrb 、 y / ho 、 zr艦f以及nb / ta發生明顯分異,暗示在花崗巖巖漿的演化過程中,經歷了充分的流體一熔體作用,同時分異出大量富含f 、 w等礦化劑元素和成礦元素的熱液流體,致使鎢礦的形成。The paper discusses dynamical conditions of the supercritical ore - forming fluid system based on study of regional geological background and analyses of physiochemical conditions of ore - forming process and puts forth the ore - forming mechanism : upper mantle uplift - mingling of meteoric water and magmatic hydrothermal fluid separated from acidic magma under tensile or transitional tensile environment - water / rock reaction - transportation - chemical coupling ore precipitation
在分析超臨界成礦流體系統形成的區域地質背景和研究成礦物理化學條件的基礎上,探討了超臨界成礦流體系統形成的動力學條件,提出該系統的成礦機理:與燕山晚期酸性火山侵入巖漿有關的金銅礦床是在上地慢隆起、張性或向張性過渡背景下形成的,酸性巖漿經熔體流體分離作用形成的巖漿熱液與大氣降水混合,經水巖作用等復雜的輸運和化學反應耦合過程的動力學產物。I ' ve seen the stream of lava from a volcano
我見過火山噴發出的熔巖流。It has been 15 years since this part of hawaii has seen lava flow like this
這是十五年來這個夏威夷區域首次出現這樣的熔巖流。( 4 ) the trace elements and ree geochemistry of the tongchang granodiorite porphyry indicate, there exists the reaction between the porphyry and the hydrothermal fluid. the hydrothermal fluid was cl - enriched solution, and flowed from the porphyry center to contact zone
( 4 )德興銅廠斑巖體微量元素和稀土元素地球化學特徵表明,該巖體發生了流體?熔體作用,分異出來的流體是一種相對富氯的流體,同時成礦流體的流向是從巖體中心向接觸帶方向流動。Lava flowed out of the crater
