iherzolite meaning in English
铬尖晶石二辉橄榄岩
Examples
- The xenoliths in the yangyuan , including iherzolite and harzburgite , represent the direct samples from the upper mantle beneath western north china craton
阳原幔源包体包括二辉橄榄岩和方辉橄榄岩，是华北西部上地幔的直接样品。 - The mafic rocks have high ( 87sr / 86sr ) j ( 0 . 7046 - 0 . 7077 ) and 207pb / 204pb ( 15 . 47 - 15 . 67 ) , but relatively low in ( 143nd / 144nd ) i ( 0 . 5125 - 0 . 5127 ) and 206pb / 204pb ( 18 . 26 - 18 . 52 ) . the negative correlation between 143nd / 144nd and 206pb / 204pb and the positive relationship between 87sr / 86sr - 206pb / 204pb suggest a mixing of a depleted mantle source and an em2 component in the study area . calculation reveals that the maopin - shaianjiao mafic rocks are formed by 5 - 15 % degree of partial melting of an lree - riched spinel iherzolite
模拟计算表明，该基性岩墙群是尖晶石二辉橄榄岩地幔5 - 15部分熔融的产物；微量元素配分模式及理论模拟表明茅坪?晒鞍角基性岩体的地幔源区在熔融前曾受到1俯冲沉积物熔体的源区混染和5流体交代作用。 - Electrical conductivities of quartz , olivine , dunite , iherzolite , pyroxenite , and megaaugite were measured by virtue of the new system ; whereas , the electrical conductivity of gabbro was measured by means of the old one . an interesting outgrowth of the present study is the measurement of the complex impedance of a series of quartz plates with different orientations
石英(人造水晶) 、橄榄石、纯橄榄岩、辉石岩、二辉橄榄岩、巨晶辉石的电导率测量是在新的测量系统下获得的，而辉长岩的电导率测量是基于lcr仪为测量仪器的测试系统下获得的。 - On the basis of the study on the petrology , trace element , and isotopic geochemistry , the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting . one is the basanite - alkaline basalt - olivine tholeiite magma series , which are generated by partial melting from spinel iherzolite ; the other is nephelinite magma - alkaline picritic basalt magma , which are generated by partial melting of the garnet iherzolite
岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。
