以新生代板内侵入岩成因与高原隆升机制之间的关系为核心科学问题，针对羌塘中部特殊的深部地壳和地幔组成、结构和热状态以及新生代大陆内部构造背景，选择该区沱沱河地区唐古拉山、祖尔肯乌拉山、乌兰乌拉山和风火山等地的新生代侵入岩及深源包体进行野外地质调查和室内矿物学、岩石学、年代学、微量元素和多元同位素地球化学示踪研究，并结合青藏高原最新的地质、岩石与地球物理资料：建立该区新生代岩浆岩时空格架, 查明其源区组成、热冷却历史及成矿潜力，揭示该区新生代深部地壳和地幔的组成、热状态以及地壳增厚、东西伸展和高原隆升的过程，探讨羌塘高原新生代深部动力学演化过程及其与高原隆升机制之间的关系，为新生代大陆板内构造-岩浆-成矿作用的理论研究提供可借鉴的典型实例，为大陆动力学理论的发展积累资料。通过5年项目实施，拟发表国际SCI论文15-20篇，促进青年人才成长，建立一支具有重要国际影响力的青藏中北部地质研究队伍。

The core scientific question to be addressed in this project is the relationship between the petrogenesis of Cenozoic within-plate intrusive rocks and deep geodynamic mechanism responsible for surface uplift of the Qiangtang Plateau. The deep crust and mantle beneath Cenozoic central Qiangtang Block, central Tibet, has been characterized by distinctive constituents, structures and thermal states related to a continental intraplate tectonic setting. In this project, Cenozoic intrusive rocks and associated enclaves in the Tanggula, Zuerkenwula, Wulanwula and Fenghuo Mountains of the Tuotuohe area, central Qiangtang Block will be subject to detailed investigations in the field. Subsequent laboratory studies on mineralogy, petrology, chronology, and major, trace and isotope geochemistry, combined with the newest geological, petrological and geophysical data, are expected to: (1) establish the temporal and spatial framework for Cenozic magmatic rocks in the Tuotuohe area; (2) determine their source constituents, thermal cooling history and metallogenetic potential; (3) reveal the constituents and thermal states of the deep crust and mantle in this area, and the processes responsible for crustal thickening, east-west extension and surface uplift of the plateau; (4) clarify the relationships between Cenozoic deep geodynamic processes and the mechanism for surface uplift of the Qiangtang Plateau; (5) establish a framework for future research on Cenozoic continental intraplate tectonism-magmatism-metallogenesis, and data collection for the development of continental dynamic theory. The project will provide significant scientific outputs throughout its 5-year lifespan, including the publication of 15-20 international SCI papers, promoting the growth of talented young scientists, and establishing a central and northern Tibetan Plateau geological research group with significant international influence.
