项目摘要

This project aimed to clarify characteristics of tectonics along the Indo-Eurasia boundary based on interpretation of active faults and their movements using the intelligent satellite photographs. Merits of using the satellite photographs for geomorphological studies in under-developing countries were discussed in detailed.Comparing the quality of air photographs, the satellite photographs and imageries, it is concluded that stereo sets of the satellite photographs are powerful enough to read low relief across active faults, and that they are only affordable data source now freely available to the workers.Interpretation of the satellite photographs revealed many unknown active faults in the study area, including the active fault system which extend from the Himalayan foothill of SE Nepal to Bangladesh, and fault traces in NW Nepal which connects the Karakoram fault and the strike-slip fault system in the Nepal Himalaya. This finding suggests that an extensive transcurrent fault system is important active faulting across the Himalaya instead of geologically well-known large scale over-thrusting which formed the geological framework of the range.Many new fault traces are also revealed along the frontal zone of the Himalaya, especially in the area where no workers carried out fieldwork such as foot-hill zones of NW India.

本项目旨在利用智能卫星照片对活动断层及其运动进行解释，阐明印度-欧亚大陆边界构造特征。详细讨论了利用卫星照片进行欠发达国家地貌学研究的优点。比较航空照片、卫星照片和图像的质量，得出的结论是，卫星照片的立体图像集足够强大，可以读取活动断层的低地形，而且它们是目前工作人员免费获得的唯一负担得起的数据源。卫星图像的解译揭示了研究区内许多未知的活动断层，包括从尼泊尔东南部喜马拉雅山麓延伸至孟加拉国的活动断层系统，以及尼泊尔西北部连接喀喇昆仑断层和尼泊尔喜马拉雅走滑断层系统的断层痕迹。这一发现表明，一个广泛的横向断裂系统是贯穿喜马拉雅山脉的重要活动断裂，而不是地质上众所周知的形成该山脉地质格架的大规模逆冲断层。沿着喜马拉雅的锋面带也发现了许多新的断层痕迹，特别是在没有工人进行野外工作的地区，如印度西北部的山麓带。
