遥感地质解译的应用与工作方法——以内蒙六户1∶5万区域矿产地质调查项目为例

Application of Remote Sensing Geological Interpretation——Setting Geological Survey Project of Regional Minerals with the Scale of 1∶50000 in Liuhu Area in Inner Mongolia as an Example

摘要:

遥感解译工作在区域地质调查中发挥了不可忽视的作用，通过对内蒙古1∶5万六户等四幅进行矿产调查，对该地区地表覆盖严重的地区进行了地质解译、图像处理和多波段数据采集分析。由于调查区覆盖严重、可解译性差，因此研究除注重技术方法的先进性，还注重与野外调查相配合。在研究初期与验证阶段都进行了大量的野外调查工作，在很大程度上提高了解译目标的针对性和解译成果的准确性。该次研究成功区分地层、侵入岩、构造的相互关系。经野外验证，在地质体展布与断裂解译方面较为准确，达到了较好的地质效果,大大提高了区域地质调查和编图的速度及质量，成为该区域地质工作的重要方法手段。

Abstract:

Remote sensing interpretation work played an important role in regional geological survey. Through geological survey work of four maps with the scale of 1∶50000 in Liuhu area in Inner Mongolia, surface geological interpretation, image processing and multiband data acquisition in serious covering areas have been carried out. Dure to serious covering and poor interpretation, advanced technology, the coordination and field survey should be paid more attention. A large number of field investigations have been carried out in the early stage of research and verification. It has improved the accuracy of the translation results in a large extent. The study successfully distinguished the relationship between strata, intrusive rocks and structures. Through field verification, it is more accurate in geological body distribution and fracture interpretation, achieves better geological effect, and greatly improves the speed and quality of regional geological survey and mapping. It has become an important means in regional geological work.
