DYNAMIC MECHANISM OF NAPPE STRUCTURES IN THE SOUTHWEST OF FUJIAN PROVINCE—TAKING THE GUANGPING NAPPE STRUCTURE AS AN EXAMPLE

摘要: 闽西南地区推覆(滑脱)构造广泛发育,存在拆离和逆冲推覆构造2种基本类型。广平地区逆冲推覆构造是闽西南地区推覆构造的组成部分,属中深层次逆冲推覆构造,其形成和演化受闽西南地区乃至福建和整个华南地区板块构造动力学背景的制约。广平推覆构造的形成和演化经历了海西期的陆内裂陷阶段(D3-P2),早印支期的伸展滑脱—挤压变形滑动构造阶段(T1-2),晚印支期向斜构造发育阶段(T3),早燕山早期裂陷和晚期逆冲推覆构造阶段(J1-2),晚燕山早期隆升造山剥蚀和晚期差异沉降阶段(J3-K)以及喜马拉雅期的隆升剥蚀阶段(E-Q)。Abstract: Nappe structures spread widely in the southwest of Fujian Province.There are 2 basic types:decoupling decollement and thrust nappe.The middle-deep thrust nappe structure in Guangping is part of nappe structures in the southwest of Fujian.Its generation and evolution,influenced by plate tectonic dynamic backgrounds in southwestern Fujian and even the whole Fujian and China,have experienced 6 stages:Hercynian intracontinental lifting(D3-P2);early Indo-Chinese extension decollement-compression deformation gliding(T1-2);late Indo-Chinese synclinal structure generation(T3);early Yanshanian early lifting and late thrust nappe(J1-2);late Yanshanian early lifting and erosion and late differential settlement(J3-K);and Himalayan uplift-erosion(E-Q).
