Discussion on Cathaysian Metallogenic Province
摘要
Abstract
This paper gives a brief discussion on the Cathaysian Metallogenic Province with strategic mineral resources holding an important position,which was definited in the monograph of the"Mineral Geology of China:Tectonic Evolution and Mineralization in South China Ocean—Marginal Pacific Ocean"(2020):① The Cathaysian Metallogenic Province is located in an extensive composite zone between the Paleo-South China Ocean Metallogenic Domain and the Marginal Pacific Metallogenic Domain,which underwent the development and evolution of the Early-Craton→South China Ocean rift system→epicontinental sea→continent since the Early Precambrian.Furthermore,it was subjected to multiphase orogeny,especially the extremely extensive Yanshanian intracontinental activation orogeny,being the world-class tungsten geochemical block,which forms the superior metallogenic genetics.② Major metallogenic characteristics:including South China Ocean and it's metallogenic of marginal arc depression remnant,and the large-scale sedimentary metallogenitc during the Nanhua interglacial period and post-glacial period;multiphase and large-scale S-type magmatic metallogenic was predominated by the tungsten,secondly,nonferrous metal,uranium,precious metals and non-metallic;I-types magmatic mineralization is dominated by copper,with iron,nonferrous metals and precious metals,as well as the super-large ore concentrated group along the Qinzhou—Hangzhou metallogenic belt,which has become an"eye"for prospecting in the"deepth",etc.③ During the Yanshanian Movement,the magmatic and metallogenic"core—mantle"type spacial—temporal evolution regularity,as well as multi-system composite tectonic framework present the dynamic system,mainly due to the left-lateral shear between the continent and ocean with combination of ocean subduction,intracontinental multidirection convergence and crustal creep effect.关键词
