the basic and ultra-basic rocks are comparable to a modern ophiolite suite and make up of an ophiolitic mélange in the strongly deformed gneiss.
这些巖石组合与现代蛇绿巖套一致 ,和强烈剪切变形的片麻巖一起构成典型的蛇绿巖混杂巖。
kudi ophiolite suite is composed of ultramafic rocks, gabbro, mantle source granitoid, basic volcanic rocks and flysch. it was formed during sinian and cambrian.
all of the petrographical, petrochemical, geochemical characteristics and ree pattern show that this ophiolite suite was formed in the caledonian eugcosyncline-back-arc basin.
巖石学、巖石化学、地球化学及稀土模式特征均表明该巖套是在加里东优地槽——弧后盆地中形成的;
they point out the age of ophiolite suite by paleontological method and the emplacement age of ophiolitic melange.
提出当前用古生物法确定蛇绿巖套形成时代及蛇绿混杂巖定位时代应注意的问题。
based on petrological and geochemical characters of ree and some inert miner elements, it is suggested here th at the basalt′s of the ophiolite suite is of oceanic ridge type.
其巖石学和ree与相对惰性微量元素的地球化学特征表明,该蛇绿巖中的玄武巖属洋脊型;
the pyrite type cu-au-deposit is located in the ophiolite suite of the precambrian bikou group.
