本文试图探索我国东南沿海板块构造活动特征与沉积—变形—变质作用、岩浆活动和矿化特征的有机联系。根据太平洋板块由陆向海(由西往东)呈现后退式俯冲的方式,将我国东南沿海区划分为绍兴—江山北东向晋宁期古板块俯冲带、丽水—海丰北北东向加里东—印支期板块俯冲带和台湾海峡北北东向燕山期板块俯冲带,并且建立了板块构造控岩控矿的理想模式。此外,还着重强调了板块构造活动的远程效应对该区岩浆岩和矿产分布的控制作用。
This paper attempts to explore the organic relationship between tectonic activity and the sedimentary-deformation-metamorphism, magmatic activity and mineralization in the southeast coast of China. According to the backward subduction of the Pacific plate from the seaward to the west (from west to east), the southeastern coastal areas of our country are divided into the subduction zone of Shaoxing-Jinning northeast of the Jinning Period, the northeast of Lishui-Haifeng, the Caledonian- Indosinian plate subduction zone and the North-East Ninth-trending Yanshanian subduction zone in the Taiwan Strait, and an ideal model for controlling the tectonism of the plate tectonics is established. In addition, the long-range effect of tectonic activities on the control of the distribution of magmatic rocks and minerals in the area has also been highlighted.
