This may be up to 50km thick and comprises ultrabasic peridotite . 其厚度可達(dá)50公里并由超基性的橄欖巖所組成。
The ultrabasic bodies are generally concordant intrusions, with related feeder dikes . 超基性巖一般為具有補(bǔ)給巖墻的整合侵入體。
Further imbrication, folding and metasomatism of the ultrabasic rocks occurred at this time . 超基性巖的進(jìn)一步疊瓦作用,褶曲和交代作用發(fā)生于這個(gè)時(shí)期。
The ultrabasic rocks form a complex of large tectonic slices with intercalated slices of sebakwian sedimentary rocks . 超基性巖與塞巴奎沉積巖巖片相間構(gòu)成一巨大的構(gòu)造巖片的雜巖體。
Many ultrabasic bodies in the orogenic association occur along strike faults, which gives a simulated concordant relationship . 與造山運(yùn)動(dòng)共生的許多超基性巖體沿著走向斷層出露,表現(xiàn)出假的整合關(guān)系。
The parefin 4 chromite claims near the northern end of the csardas thrust again indicate the eastward extension of the thinning ultrabasic sheet from railway block . 靠近薩達(dá)斯沖斷層北端的帕勒芬4鉻礦區(qū)又表明從鐵路段向東超基性巖席減薄的情況。
Geochemical features of xiangshan basic - ultrabasic rocks in guangxi , china 廣西香山巖體地球化學(xué)特征
In this thesis , studies show that the xigou ultrabasic rock body is a synthetic ore deposit composed of serpentinite ores , decorative stone ores , metallic and precious metallic ores 本文實(shí)例(西溝超基性巖體)研究,較系統(tǒng)地查證西溝超基性巖體為一頗具資源潛力的綜合性“礦床” 。
However , compared with jinchuan ore - bearing intrusion , jianchaling ultrabasic intrusion formed by magma simple emplacement , and magma fractionated weakly with lower content of nickel and sulphur 而與賦存超大型鎳銅硫化物礦床的金川巖體相比,煎茶嶺超基性巖體為巖漿一次侵位形成,分異程度小,鎳、硫含量較低。
The main source of nickel and platinum metals in the world is the nickel - copper sulfide magmatic deposits related to basic - ultrabasic body , which provide half or more amount of the metals in the world 世界鎳和鉑族金屬的主要來(lái)源是與基性超基性巖有關(guān)的銅鎳硫化物巖漿礦床。該類(lèi)礦床占世界鎳、鉑量的近一半或更多。
