摘要
测区为第四系覆盖,地层分界不明显,断层错综等地质条件复杂,且附近有高压输电线、国道等强干扰地区深部进行地热勘查。通过收集和分析测区已有地质资料,确定该区地热成矿模型,采用高密度电法和广域电磁法相结合,提高成果分辨率,划分出地层分界和断层等地质信息,推断出地热成矿有利部位。经钻探验证,取得较好的地热勘查效果。
This study area is not only covered by Quaternary strata,with unclear stratigraphic division and complex faults,but also strongly interfered by high-voltage transmission lines and corridors in deep geothermal exploration.Through collecting and analyzing the existing geological materials in the survey area,the geothermal metallogenic model of the area was constructed.The combination of high-density electrical method and wide field electromagnetic method was used to improve the resolution of the results,divide the geological information such as stratigraphic and fault,and infer the favorable position of geothermal mineralization.It has been proved by drilling that good geothermal exploration effect can be achieved.
