福建省推覆构造研究及其意义

本文主要是根据“闽西南地区推覆构造与隐伏煤田预测研究”的主要成果来写的。在概述两次研究课题取得主要成果的同时，对福建省重大基础地质有关的问题提出了新的认识。文中重点是总结了福建省推覆构造发育的特征，将推覆构造划分为两大类（逆冲推覆构造，拆离构造）和五种类型（中深层次逆冲推覆构造、浅层次逆冲推覆构造、褶皱逆冲推覆构造和拆离（滑脱）构造、褶皱拆离构造），对各类型的主要特征、分布规律、组合特征和推覆构造的发生和发展进行系统的总结，明确指出了燕山早期中深层次边冲推覆构造是福建省规模最大、对今后寻找隐伏矿产关系最密切和最重要的推覆构造，对研究我省的推覆构造具有重要意义。并结合福建省的实际，从基础地质和找矿两方面进行论述。

Nappe Structure Research of Fujian Province and its Significance

This poper reports on the research works of nappe structures and concealed coalfield prospect in southeast6rn Fujian and sums up the development characteristics of nappe structures in Fujian Province.The nappe structures in Fujian Province can be divided into two major kinds (thrusting and decollementnappe structures) and five types (intermediate depth, shallow thrust nappe structures, fold thrust nappestructure, decollement and decollement fold structures). In the paper, the authors made a discussion on the main characteristics, distribution and associated relation of these type of nappe structures, as well as the formation and development of the nappe structures, The intermediate depth thrusting nappe structures of early Yanshanian are considered to be the largest and mest important nappe structures in Fujian Province, which have more close relationship to prospecting hidden deposits in the future. This is of significance to study of nappe structures in Fujian Province.
