对辽西阜新地区晚太古宙韧性剪切变形变质岩石岩石学,常量、微量和稀土元素地球化学和矿物学的研究表明,在中地壳环境下的韧性剪切变形变质进程中,岩石中的元素都发生了不同程度的变异,主要表现为随变形强度的增加SiO2,Na2O,Zr等组分规律性减少,而Al2O3,CaO,FeO,MgO等常量元素、稀土元素以及Ba,Cr,Sr,Ni,Rb等微量元素规律性增加,本文认为剪切变形变质岩石的成分变异不仅仅是流体作用的结果,而且与剪切变形变质过程中的体积亏损相关。
Studies on the geochemistry and mineralogy of the Late Proterozoic ductile shear deformation metamorphic rocks in the Fuxin area, western Liaoning Province, show that in the processes of ductile shear deformation and metamorphism in the mid-crust, all the elements in the rocks The variation of SiO2, Na2O, Zr and other components decreased with the increase of deformation strength. However, the regular elements such as Al2O3, CaO, FeO and MgO, rare earth elements and the contents of Ba, Cr, Sr, Ni, Rb and other trace elements regularity increase, the paper that the composition of shear deformation of metamorphic rocks is not only the result of the fluid effect, but also with the volume loss during shear deformation and metamorphism.
