摘　　要：苏北青湖地区位于郯庐断裂以东的苏鲁造山带内,为大别—苏鲁超高压变质带东延部分,是一个长期隆起遭受剥蚀的地区。为了查明青湖地区地质构造条件并预测该区地热资源远景情况,本文在充分收集地质资料的基础上,采用可控源音频大地电磁法(CSAMT)、地温测量和氡气测量方法对区内构造断裂进行研究,并进行了地质-物探综合解译。经综合分析研究,得出了青湖地区的断裂构造展布特征和地热地质条件,预测了地热资源远景区,并建议了地热井位。CSAMT、地温测量和氡气测量方法联合勘查地热资源可相互作证,能进一步提高变质岩地区地热资源靶区预测的可靠性。本研究可为今后该区及相似地区的深部勘查地热工作提供一定的参考和借鉴。The Qinghu area in northern Jiangsu Province is located in the Sulu orogenic belt to the east of the Tanlu fault.It is the eastward extension of the Dabie-Sulu ultrahigh pressure metamorphic belt.In order to ascertain the geological structural conditions and predict the geothermal resources in the Qinghu area.On the basis of fully collecting geological data,this paper uses the Controlled Source Audio-frequency Magnetotellurics(CSAMT),geothermal measurement and radon gas measurement to study the structural faults in this area,and conduct a comprehensive interpretation of geology and geophysical exploration.We carried out a comprehensive interpretation of geology and geophysical exploration.Through comprehensive analysis and study,the distribution characteristics of fault structures and geothermal geological conditions in the Qinghu area are obtained,the geothermal resource prospect area is predicted and the geothermal well location is suggested.The combined exploration of geothermal resources by CSAMT,geothermal measurement and radon gas measurement can prove each other,and can further improve the reliability of geothermal resource target prediction in metamorphic rock areas.This study provides a certain reference for future deep exploration geothermal work in this area and similar areas.
