鄂东白莲河地区共轭构造地质特征及成因

GEOLOGICAL CHARACTERISTICS AND GENESIS OF THE CONJUGATE STRUCTURES IN BAILIANHE AREA,EASTERN HUBEI

根据区调及有关资料 ,对白莲河地区普遍发育的共轭韧性剪切系统及共轭脆性断层系统的分布规律、产出状态、地质特征及成因进行了初步总结和探讨 ,认为区内共轭构造是在印支运动南北挤压作用下形成的剪裂面 ,经燕山期强烈活动而最终形成的。共轭构造控制了区内地层展布、岩浆活动、变形变质作用及地貌特征。

Conjugate ductile shear system and conjugate brittle shear system, widely developed in Bailianhe area , Hubei,are initially summarized and discussed in aspects of their distribution law, occurrence, geological features and genesis.It is concluds that, undergoing the strong activity in Yanshanian,the shear factures, formed by S-N compressing during Indosinian movement , were transfered into the conjugate structures which have controlled the stratigraphic distribution, magamatic activity, deformation- metamorphic process and geomorphic features in this area.
