用遥感技术研究贺兰山区构造

STUDY ON THE THRUST SYSTEM WITH REMOTE SENSING TECHNIQUES IN HELANSHAN DISTRICT

在前人资料的基础上,通过对典型地质体的反射波谱测试,TM图象解译及野外调查,建立了推覆构造的影象解译标志,认为该区为一双冲推覆构造体系,推覆面积不小于8000km^2,推覆距离至少50km。这一新认识对于该区煤田预测有重要意义。

The reflective spectral values of the major geologic bodies in Helanshan District were measured, the TM false color images were interpreted and a field investigation was made. Then the interpretation keys of thrust system on the TM images were set up. As a result of above the author considers that in the study area occurs a the range of the duplex isn't less than 8000 km^2, and the thrusted distance is more than 50 km. This new conclusion will be of great geologic significance for the exploration of coal fields.
