Numerical Modeling of Strain Histories and Displacement Paths in Compressional Orogens

9805021该项目是一项雄心勃勃的尝试，旨在模拟挤压造山过程的几个方面，特别是晚期同造山和/或造山后伸展的原因，将挤压位移划分为走滑和倾滑成分，并建立一个根据地质和地球物理观测解释岩石位移历史的基础。这项工作涉及一系列先是二维的有限元模型，然后扩展到三维，然后测试并应用于许多造山带，包括瓦奇塔和布鲁克斯山脉。这些结果有望帮助理解造山运动中长时间斜向会聚的结构反应。

9805021 Harry This project is an ambitious attempt to model several aspects of the compressional mountain building process, especially the causes of late stage syn- and/or post-orogenic extension, the partitioning of transpressional displacement into strike-slip and dip slip components, and on developing a basis for interpreting rock displacement histories from geologic and geophysical observations. The work involves a series of Finite Element models in first 2-D and then expanded to 3-D followed by testing and application to a number of orogens, including the Ouachita and Brooks Range. Results are expected to help understand structural response to prolonged oblique convergence in orogenesis.
