9628074 Kong Recent studies have indicated that large changes occur in strain distribution or partitioning and strain accommodation during the evolution of a collisional event. This project will attempt to model dynamic causes for major spatial and temporal changes in strain distribution and initiation of major intracontinental faults in Asia during Indo-Asian collision. In order to evaluate the role of various input factors, the work will use a newly developed finite element technique to simulate both the evolution of major fault systems and related deformation within major continental blocks. Faults will be sequentially introduced into the model according to their ages determined by recent geochronologic studies. The resultant systematic restoration of both distributed deformation and discrete fault movement will allow a rigorous evaluation of dynamic causes for the changes in tectonic styles and strain distribution in Asia during the Indo-Asian collision.

9628074 KONG最近的研究表明，在碰撞事件的演变中，应变分布或分配和应变适应发生时发生了巨大变化。 该项目将尝试建模在印度 - 亚洲碰撞期间，亚洲主要肠内断层的应变分布的重大空间和时间变化的动态原因。 为了评估各种输入因素的作用，该工作将使用新开发的有限元技术来模拟主要大陆块内主要断层系统和相关变形的演变。 故障将根据最近的年代学研究确定的年龄将故障依次引入模型。 所得的系统恢复分布式变形和离散断层运动将允许对印度亚洲碰撞期间亚洲的构造样式变化和应变分布的变化进行严格评估。
