母巖漿
英文
mother magma-
Granites belong to s - type granite, but the biotite granite was affected by the mantle or mantle fluid
黑雲母花崗巖是殼源花崗巖但又受到幔源巖漿或幔源流體的影響。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。There are two stages to crux maifan stone ' s formation, the first stage is the forming stage of primary material, that is to say, the stage of mother rock formation, in this stage, the latter hypabyssal intrusive of crystallization fractionation and self - metamorphic process are an important factor to make sure them have many trace elements
麥飯石的形成中有兩個階段是十分關鍵的,第一個階段是基本物質的形成階段,即母巖的形成階段。在這一階段中巖漿分異結晶晚期的淺成侵入以及自變質作用,是保證其富含營養微量元素的重要條件。Test of grouting and water injecting technology and its application to extinguishing spontaneous combustion of oil shale foundation soil
灌漿注水處理油母頁巖矸石地基自燃的試驗與應用Strong compatible elements, as cr, ni, co, sc, from most samples is very low
大多數樣品的cr 、 ni 、 co 、 sc等強相容元素含量較低,也暗示了形成鎂鐵質巖石的母巖漿應屬殘余熔融體。This paper mainly summarizes the tectonic setting, common features, nature of the parental magmas, genesis of rhythmic layers of various types of layered intrusions, and the important roles that magma mixing and crustal contamination play in magma evolution
文中主要總結了不同類型層狀巖體形成的構造背景、基本特徵、母巖漿特徵和韻律層理成因,以及巖漿混合和地殼混染在巖漿演化過程中起到的重要作用。分享友人
