Abstract

Linze County is located at the southwest edge of Zhangye-Minle basin and along northern central Qilian fold belt and has a good prospect for development and utilization of geothermal resources. The authors analyzed regional geological structure and hydrogeological characteristics of the study area and investigated existing geothermal well and preferred working area by the wide field electromagnetic method. Through comprehensive analysis and on the basis of regional hydrogeologic and geophysical exploration results, the distribution characteristics of geological structure and rock mass in the study area were interpreted and inferred, the prospect of geothermal exploration in the research area was analyzed and evaluated. Meanwhile,the "geology-geophysical-geothermal energy" model of geothermal exploration in the study area was preliminarily constructed. This model provides reference and guidance for geothermal exploration in the study area and adjacent areas.

Key words： hydrogeology geothermal resources wide field electromagnetic method geological structure Gansu Province
