Lithospheric Deformation of the Southern Alps in South Island, New Zealand

9805224 kohler这项研究与新西兰地质与核科学研究所合作，研究了新西兰年轻、地震活跃的南阿尔卑斯山的地壳和上地幔结构。该项目将测试年轻的跨震构造体系是否需要加厚的岩石圈、高地震速度、高密度的根作为其早期发展的一部分。主要目标是；1)获得南阿尔卑斯山地壳下岩石圈非均质性的三维地震图像；2)将层析成像图像整合到描述斜俯冲带断裂系统发育演化的更大构造框架中；3)建立一个通用的年轻造山运动热运动模型。这将通过1995-1996年南阿尔卑斯山被动地震实验数据集与新西兰国家地震网数据集相结合的远震走时反演来完成。这项研究是国家减少地震危害计划的一个组成部分

9805224KohlerThis research deals with the study of the crustal and upper mantle structure along the young, seismically active Southern Alps in New Zealand in collaboration with the New Zealand Institute of Geological and Nuclear Sciences. The project will test the question of whether young transpressional tectonic regimes require thickened lithospheric high seismic-velocity, high-density roots as part of their early development. The main objectives are; 1) to obtain three-dimensional seismic images of subcrustal lithospheric heterogeneity beneath the Southern Alps, 2) to integrate the tomography images into the larger tectonic framework describing the development and evolution of the oblique subduction zone fault system, and 3) to develop a general thermal-kinematic model of young orogeny. This will be accomplished by teleseismic travel-time inversions of the 1995-1996 Southern Alps Passive Seismic Experiment data set combined with the New Zealand National Seismograph Network data set. This research is a component of the National Earthquake Hazard Reduction Program.***
