大地电磁测深（MT）与土壤氡气测量在涡阳地区地热勘查中的应用

Application of Magnetotelluric Sounding(MT) and Thesoil Radon Measurement in Geothermal Exploration in Guoyang Area

摘要:

为了研究涡阳地区深部构造和热源条件，在高炉镇附近进行了大地电磁测深（MT）测量和土壤氡气测量工作。通过对大地电磁测深结果和土壤氡气浓度异常分布范围分析和解释，指导区内地热勘查工作。通过资料解释，基本查明区内构造的走向及其垂向延展特征，查明基底起伏变化情况并了解深断裂的控制性，预测地热成矿区有利地段。研究证明，利用MT与土壤氡气测量对隐伏断裂位置和地热异常具有较好的指示意义。

Abstract:

In order to study deep structures and heat source conditions in Guoyang area, magnetotelluric sounding (MT) and soil radon measurement have been carried out in Gaolu town. Through analysis and interpretation of magnetotelluric sounding and soil radon concentration anomaly distribution, geothermal exploration work in this area has been carried out. Through data interpretation, direction of the structures in this area, its vertical extension characteristics and the changes of basement relief have been identified, and the controlled ovarian have been understood, and favorable areas of geothermal forming have been predicted. it is showed that it has good guiding for determing the locations of buried faults and geothermal anomaly by using MT and soil radon measurement.
