摘　　要：笔者等对《中国矿产地质志·华南洋—滨太平洋构造演化与成矿》一书(2020)厘定的战略矿产资源居于重要地位的华夏成矿省作些简要论述:①该成矿省处于古华南洋成矿域与滨太平洋成矿域强烈复合地带,历经早前寒武世克拉通—华南洋—华南裂谷系—陆表海—大陆的发展演化,又受到多期造山特别是空前强烈的燕山期陆内活化造山,并且是一个世界级钨地球化学块体,构成了优越的成矿基因;②主要成矿特征:包括华南洋及其陆缘弧盆残体成矿,南华间冰期与冰后期大规模沉积成矿,多期大规模S型岩浆以钨为首的有色、铀、贵金属、非金属成矿,I型岩浆以铜为首的铁、有色、贵金属成矿以及钦杭成矿带超大矿床集群与“深地”找矿之眼等;③燕山运动岩浆与成矿“核幔式”时空演化规律以及多体系复合构造格局与陆洋左行扭动与洋壳俯冲为主导并有板内挤压、地壳蠕散相复合的动力学机制。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):①The 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.②Major 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.③During 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.
