| 摘 要： | 岩石的应变组构型式与岩石成分、变形环境和应变过程有着密切关系。北瓦沟地区低角闪岩相条作下的长英质岩石,表现脆性、韧性和韧脆性过渡,因而在剪切作用过程中形成了相应的应变组构型式,即脆性应变组构、韧性应变组构和脆-韧性应变组构。而且随着应变过程的发展,应变组构也表现出一定的演化规律。

| Abstract: | The styles of strain fabrics in rocks are closely associated with the components of rocks,the environment of deformation and the history of straining.Under lower amphibolite facies,the highly sheared felsic rocks from Beiwagou area can be of brittle,ductile or brittle-ductile transition,with the occurrences of corresponding strain fabrics formed during the early shearing of the layered proterozoic complexes.The strain fabrics display a certain evolution regulation with the straining history. |
