岩石组 meaning in Chinese

rock group

Petrofabric determination based on image process
基于图象处理的岩石组构测定方法
Lattice preffered orientation and seismic anisotropy of ultramafic xenoliths in damaping , hebei province
河北大麻坪超基性岩包体的岩石组构和地震波速各向异性
Directions are obtained by two means : calculation and measure . our investigations are summed as follows : 1 the lpo relations between olivine and orthopyroxene are different from usually situations : 100ol 001opx , 010ol 100opx , 001ol 010opx ; 2 the seismic anisotropy of the ultramafic rocks in damaping is obvious . their characters are consistent with the structures of the rocks and fabrics of minerals , which means seismic anisotropy is mainly controlled by rocks fabrics ; 3 seismic velocities suggest that the composition of upper mantle in damaping region is resemble to the xenoliths , which major component is lherzolite
不同2大麻坪地区幔源包体的波速各向异性显著，岩石的波速各向异性特征与其宏观构造和微观组构一致，说明岩石组构是造成地震波速各向异性的决定因素3由地震波速推测的大麻坪地区的上地幔成分与包体出露的情况一致，即主体为二辉橄榄岩。
