felsic meaning in Chinese
长英矿物
长英质的
Examples
- Metallogenic models of cu , ag deposits in felsic volcanic rock of permian continental facies of awulale , western tianshan mt
西天山阿吾拉勒二叠纪陆相长英质火山岩铜银矿矿床模式 - All the mafic and felsic volcanic - hosted massive sulfide deposits are therefore defined as the kunlun type volcanic - hosted massive copper sulfide deposit
这些基性火山岩型和酸性火山岩型矿床被统称为昆仑式火山岩型块状硫化物铜矿床。 - A large number of studies of geochronology and geochemistry indicate that mesozoic intermediate - felsic rocks from the dabie orogen have originated from recycling of the subducted yangtze continental crust itself
摘要大量的同位素地质年代学和地球化学研究表明，大别山中生代中酸性岩为俯冲扬子陆壳再循环的产物。 - All of the mafic samples have age - corrected moderate enriched sr and enriched nd isotopic ratios and the felsic rocks span larger range in the initial sr and nd isotopic ratios than mafic volcanics , similar to isotopic compositions of lower crust of north china block
在sr - nd同位素组成上，中基性火山岩为中等富集的sr和低的nd同位素比值；中酸性火山岩的sr同位素比值总体较中基性岩高且变化大，类似华北陆块下地壳岩石的同位素组成特征。 - These deposits , which can be obviously divided into basic and acid volcanic types , are present in the carboniferous bi - model volcanic series and occur along two horizons , i . e . , the lower carboniferous mafic volcanic rock and the upper carboniferous felsic volcanic rock
这些矿床产在石炭系双峰式火山岩系之内，沿著下石炭统基性火山岩和上石炭统酸性火山岩两个层位产出，分别以玄武岩和流纹岩为容矿主岩，可以明显地分成基性火山岩型和酸性火山岩型两种类型。
