中文拼音 [yánjiānghúnrǎn]
巖漿混染
英文
magma contamination-
During the magma evol ution, this primary magma suffered effects of the containing water fluid and a small extent contaminate of continental crust. according to all of features above, the paper analyzes the formatting mechanism of high - mg volcanic rocks
巖漿演化過程中遭受到了含水流體的影響及輕微的陸殼混染。根據以上特徵對高鎂火山巖的形成機製作了分析。Jianchaling nickel deposit that respected with it is originally devided into magma type deposit, its metallogenesis include magma differrentiation - crystalization, sulfurization process, magma melt - segregated, and hydrothermal process. but melt - separated ore - forming poorly developed, and hydrothermal process is subordinate, the assimilation and contamination of country rocks have special significance to the formation of this ore deposit
與之有關的煎茶嶺鎳礦床成因上屬巖漿礦床,其成礦作用有巖漿分結作用、硫化作用、巖漿熔離作用及熱液作用等,但巖漿熔離成礦作用不發育,熱液作用僅佔次要地位,富硫圍巖的同化混染對礦床的形成有特殊的意義。Layered mafic intrusions not only represent natural laboratories for studying processes of magmatic differentiation and assimilation within the crust, but also contain extensive precious and base metal mineralization
層狀鎂鐵質巖體不僅是研究巖漿分異演化過程和地殼混染作用的最佳天然實驗室,其中還廣泛賦存重要的稀有金屬和賤金屬礦床。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。The high nb and zr contents, as well as em2 signature, may have been resulted from addition about 1 % melts derived from subducted sediments
基性巖漿在上升過程中還受到10左右的地殼物質的混染作用,導致該區基性巖富放射成因sr 、 pb同位素。Cu - ni sulfided mine complex locate in baimazai of jinping county is sub alkali iron - super iron, it ' s zoning is clear and it ' s ni - cu - co melting first and enrichment, its rare earth is rich in right lean light rare earth, but eu in olive rock is serious to be bad, gd - tb is tittles negative abnormity. above - mentioned show that the mineral is cone from mantle, and didn " t mix with crustal substance, and continent tholeiite magma turning into continent tholeiite emplacement after by surging
金平白馬寨銅鎳硫化礦床雜巖體分帶明顯、屬亞堿性鐵質-超鐵質巖、具ni - cu - co三元素先熔離,后富集的規律、稀土配分為右傾斜輕稀土富集型,但橄欖巖銪虧損顯著, gd - tb微小負異常,顯示成礦物質來源地幔,與地殼物質無混染和大陸拉斑玄武巖漿上涌后變為大洋拉斑玄武巖漿侵位特點。6. on the ground of all these research works, we studied the magma crystallization - assimilationary mechanism that works on the shandong sapphire and its bands, we also analysed the relationship between this mechanism and the isolated or open condition
6 、在上述研究基礎上,討論了山東昌樂藍寶石及其環帶形成的巖漿結晶-同化混染聯合作用機制及其與封閉開放條件的關系。分享友人
