摘　　要：广州花都地区地热资源丰富,但深部地热类型以及分布不清。为了解决这一问题,将广域电磁法应用于广州花都地热勘查,设计了3条测线进行数据采集。通过反演结果,认为研究区存在两种地热类型,分别为浅层花岗岩破碎风化层以及下覆的完整岩体,整体属于薄盖层地热田。其中浅部的破碎含水花岗岩地区,沿着区域断层F2分布,为水热型地热的有利勘查区。深部完整的花岗岩地区是潜在的干热岩型地热有利勘查区。The Huadu area of Guangzhou is rich in geothermal resources,while the type and distribution of deep geothermal are unclear.In this paper,the wide field electrical method(WFEM)is applied in the geothermal exploration of Huadu area of Guanghzou.There survey lines have been designed for the data collection.According to the resistivity inversion results,the analysis shows that there are two geothermal types named shallow fractured granite and the underlying whole granite rock.have been divided are the two types of the geothermal reservoir.The shallow area distributed along the regional fault F2,is a favorable exploration area for hydrothermal geothermal.The deep granite area is a potential favorable exploration area for hot-dry rock geothermal.
