TECTONIC FRAMEWORK OF NAPPES IN THE SUI ZAO AREA,HUBEI PROVINCE

Publish Date: 15 February 1997

摘要: 研究区构造格局的基本特征是上地壳多层次自北而南的逆冲—拆离，柳林、洪清、大洪山３条逆掩断层与深部拆离面一起组成了尖端指向南的楔形薄皮构造。逆冲系统以背驮式扩展演化。多层次推覆构造格局因后期高角度断裂的切割破坏而复杂化，构造格局定型时代为燕山期
Abstract: The basic feature of the tectonic framework in the Sui Zao area,Hubei,is the south directed multi level thrusting detachment of the upper crust.The Liulin,Hongqing and Dahongshan overthrusts together with the deep level detachments form the south pointed wedge shaped thin skin structure.The thrust system is characterized by backpack expansion.The multi level nappe tectonic framework was complicated by cutting and destruction due to late stage high angle fracturing,and the tectonic framework was finalized in the Yanshanian.
