摘要
沙泉子地区的地质环境较为复杂,区域面积较大,基岩出露条件良好,为遥感技术的应用提供了良好条件。以Landsat-7 ETM影像作为影像数据源,通过对遥感影像的预处理和增强处理,结合区域地质背景建立了区域地质体及构造的遥感地质解译标志,完成了研究区岩性地层解译和地质构造解译,对区域1∶200 000地质图进行了补充修正,为该地区的资源勘查、区域填图、成矿预测和分析提供了一定依据。
The geological environment of Sha Quanzi district is comparatively complex, the district area is large, and the outcrop condition of bedrock is highly qualified, thus good prerequisite of application of remote sensing technology was provided. In this paper, on the basis of Land - 7 ETM image taken as image data source, through pre-processing and enhancement processing of remote sensing image, the regional geological body and remote sensing regional interpretation signal were established combined with the regional geological background, and the lithological strata and geological formation of studied area were interpreted. The 1：200000 geological map of the district was revised,which provide certain references for the resources exploration,regional mapping,metallogenic forecasting and analysis in this area.
