四川广元地区1∶5万区域地质调查的遥感技术应用

The Application of Remote Sensing Technology to 150,000 Regional Geological Survey in Guangyuan,Sichuan

通过四川广元地区1∶5万区域地质调查工作实践,论述了遥感技术的应用和工作方法,重点讨论了遥感地质解译方法,遥感技术在区域构造格架的建立、岩石地层单元的划分对比、地质体的填绘等方面的应用。实践表明,在1∶5万区域地质调查中应用遥感技术能使工作者在填图前获得有关地质构造的超前信息,提高工作者预测地质体的能力和圈定地质体界线的精度,达到提高工作效率和填图质量的目的。

This paper deals with the application of remote sensing technique to the 1 ： 50,000 regional geological survey in Guangyuan, Sichuan, including interpretation of remote sensing image and the application of remote sensing technique to the establishment of regional tectonic framework, division and correlation of petrostratigraphic units and geological mapping. The practice indicates that the application of remote sensing technique is of importance to the raising efficiency and quality of geological mapping.
