| The Progress of the Preliminary Compilation of Map of Mesozoic Granitoid of Asia and the Research on Related Key Issues |
| Mesozoic granitoids in Central Asian Orogenic Belt (CAOB), Central Orogenic Belt of China (COBC) and North China Craton (NCC) have been newly identified. In combination with zircon U-Pb ages and geochemical data available, the authors summarized temporal and spatial framework, genesis and source characteristics of Mesozoic granitoids in China and adjacent regions, revealed several kinds of tectonic settings, and preliminarily compiled Map of Mesozoic Granitoids of Asia on the basis of a property-driven database. Furthermore, tectonic settings of Triassic granitoids in Asia and evolution of granitic magma corresponding to Jurassic–Cretaceous transformation of the continental crust from contraction to extension in Northeast Asia were newly proposed in the light of the assemblage of Asian continent. This is for the first time that the temporal and spatial framework of Mesozoic granitoids of Asia has been summarized, and the results achieved by the authors will not only improve our knowledge on the Mesozoic tectono-magmatism of Asia but also have great significance for further studies of Mesozoic tectonic evolution and ore-forming setting of Asia. |
