    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.
