摘要
根据 1∶5万区域地质调查资料和野外重点地段的解剖研究 ,将广元 -朝天地区推覆构造划分为四个推覆构造带 ,并论述了该区推覆构造的特征及其变形模式 ;提出了区内滑覆是由推覆形成的 ,其发展方向为由北西向南东 ,扩展方式为前展式。探讨了本区推覆构造的形成演化机制。
The napple structures in Guangyuan-Chaotian region,Sichuan may be divided into 4 zones on the basis of 1:50,000 regional geological surveying and key section investigation.Features and deformation model for the nappe structures are discussed.And gliding-nappe structures in this region resulted from napping southeastwards.A genetic mechanism for the nappe structures is put forward.
