形变实验中的构造地球化学及对成矿的意义

Tectonogeochemistry in Deformation Experiments and Its Significance in Mineralization

通过对不同岩石、矿石样品进行的构造地球化学形变实验结果表明，形变中形成了典型的塑性变形组构，同时也使样品中的矿物不仅发生形貌、颜色、干涉色以及结构的改变，而且矿物化学成分也发生了明显的变化。说明形变不仅是一种构造和地球化学作用过程，同时也是一种成矿作用。

everal deformation experiments were carried out on different rock and mineral samples,Inthese experiments,typical platic deformation fabrics were formed and,in addition,a series ofchanges in appearance,color,interference color and texture were observed.The chemicalcompositions of minerals were also obviously changed.The results suggest that deformation is notonly a tectonogeochemical process,but also a kind of mineralization.
