在中亚、中央造山带、华北克拉通周边等地区，新鉴别出一批中生代花岗岩，结合收集的锆石U-Pb年龄和地球化学数据，集成已有成果，初步总结了中国及邻区中生代花岗岩时空分布框架、成因演化及物源特征，揭示出了多种构造环境，编制了基于属性数据库的亚洲中生代花岗岩地质图。从亚洲大陆拼合角度论述了三叠纪花岗岩带的构造背景；揭示了东北亚侏罗纪—白垩纪地壳由挤压增厚到伸展减薄过程中花岗质岩浆性质演变的响应关系。这是亚洲中生代花岗岩分布框架的一次尝试性总结，有助于提高亚洲中生代构造岩浆作用的整体认识，对深入探讨亚洲中生代大地构造演化和成矿背景有重要意义。

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 compiledMap 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.
