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.
