江西宜丰-德兴叠覆造山带的基本特征及其意义
摘要
Abstract
During the study and compilation of new generation of Jiangxi Regional Geology, the authors found a new kind of oro⁃genic belt type in the Yifeng-Dexing area, which is called Jinningian-Caledonian Yifeng-Dexing superimposition type orogenic belt that is spread in the semilunar tongue form. It is a concealed-semiconcealed type orogenic belt formed through N-S bidirection⁃al multi-periodic collision and superimposition. Based on studying and recovering the tense state ,site state and phase state of the tec⁃tonic slices exposed along orogenic belts, the authors established a tectonic evolution sequence model with a three-layer structure. The model of structure includes the remnants of ophiolite of South China Sea, metamorphosed volcanic sedimentary series of fore-arc basin on the Yangtze continental margin in Middle-Late Proterozoic, abyssal facies sedimentary epimetamorphic rock slice of Lower Nanhua System, and Lower Nanhua System epimetamorphic rock slice of Late Qingbaikou Period-Early Paleozoic Period in Huaiyu-Guangfeng area. Yifeng-Dexing and Jingdezhen-Yiyang nappe zone on both sides of the orogenic belt is an important ore concentration area of copper, gold polymetallic resources,and the Late Paleozoic coal seam under metamorphic strata has a huge po⁃tential in search for coal.关键词
