福安—南靖断裂带特征及其地质意义讨论

通过对沉积建造、岩浆活动、构造变动以及地球物理和地球化学综合研究,在全国统一的一、二级构造单元划分框架下,以反映早古生代末构造格局为主,福建省大致以福安—南靖断裂构造带为省内一级构造单元为边界划分西部华夏地块、东部闽浙沿海火山侵入杂岩带2个三级构造单元,讨论了福安—南靖构造带特征及其地质意义。

Discussion on the Characteristics and Geological Meanings of the Fu'an-Nanjing Fault Zone

Based on the comprehensive study of the sedimentary formation, magmatic activity, tectonic events, geophysics and geochemistry in Fujian Province, the tectonic units can be divided into the two third-grade structure units, namely, the Cathaysian block in western Fujian and the Fujian-Zhenjiang coastal volcanic intrusive complex belts in eastern Fujain, by the Fu＇an-Nanjing fault zone of the first grade structure unit, which is under the nationwide unitive division framework of the first and secondary tectonic units and can present the major tectonic framework of late Eopaleozoic. The characteristics and geological meanings of the Fu＇an-Nanjing tectonic belt are also under discussion in the paper.
