| 中文摘要: |
| 地壳中晶质矿物的化学行为主要为溶解、固相－固相反应和表面化学行为３类，剪切应力作用可以加速和促进这３类行为。其原因主要在于剪切应力作用可以改变矿物的晶格结构，增加其内部和表面缺陷。 |
| 英文摘要: |
| Chemical behaviour of crystalline minerals in the crust of earth can be classified into three main sorts:doissolutIon,solid-solid reaction and surface chemical behaviour, which are all accelerated and enhanced by shear stress.The main rcasn for this is that the shear stress can change the lattice texture and increase the inside and surface defects of the shear- stressed minerals.This kind of effect of shear stress on chemical behaviour of crystalline minerals maybe play animportant role in metamorphism, mineralization and other geochemical reaction in the shear setting. |
