During diagenetic process, there may exist the fractional crystallization of clino - pyroxene, plagioclase, olivine and ti - fe oxide, and the accumulation of olivine. the alkalic - ultramafic dikes formed by low degree partial melting ( 3. 4 % ) of enriched mantle, consist of single olivine pyroxenolite, the dominating olivine fractionation is evident
成因上為富集地幔部分熔融作用的結果,但在成巖過程中也可能存在單斜輝石、斜長石、橄欖石和ti - fe氧化物等礦物的分離結晶作用。The chromite deposits in the muskox complex occur only in feldspathic peridotite.
在穆斯科克斯雜巖體中,鉻鐵礦礦層僅產于長石質橄欖巖中。With regard to the oxide minerals, chromite is almost entirely contained in the olivine-rich ultramafic rocks in the lower part of the intrusion.
關于氧化礦物,鉻鐵礦幾乎全部含于侵入體下部的富橄欖石的超鎂鐵質巖石中。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。The determinative characteristics of common rock forming minerals containing quartz group, feldspar group, mica group, hornblende group, pyroxene group, olivine group and carbonatite minerals will be discussed in greater detail
對常見造巖礦物,如石英類、長石類、雲母類、角閃石類、輝石類、橄欖石類、碳酸鹽類礦物的鑒定特徵將予以詳細的說明。This new source of peridot displays a beauty of color and transparency not found in the earlier sources
橄欖石也是構成石隕石的主要礦物之一。橄欖石不含石英,因此不能生於花崗巖中。As magma cools, the first minerals to crystallize are olivine and pyroxene, which are rich in iron and magnesium
隨著巖漿冷卻,首先結晶出的礦物是橄欖石和輝石,富含鐵和鎂。Systematically tested, analyzed and sorted out geochemical data of intrusion - related nickel deposits in china, such as analysis of zonal structure of chrome spinels, micro - probe in situ analysis of single minerals incjude olivine and pyroxene by la - icp - ms, in which some of the research is the first time domestically
其中一些研究,如鉻尖晶石環帶的研究、橄欖石、輝石等單礦物的原位la ? icp ? ms分析等,在我國還是首次,為研究我國主要銅鎳硫化物礦床成巖成礦過程中元素的分異和演化提供了定量結果。分享友人
