摘　　要：广东惠州位于华南板块东部边缘,属东南沿海断褶带。根据野外地质调查成果,研究总结了黄沙洞地热田及周边的地质构造特征及构造演化规律,研究区经历了多期次构造运动,基本形成了以北东、北西向构造为主的“棋盘格子式”断裂构造样式群。北东、北西向构造为重要控热构造,与区内地热分布具有强烈相关性,经综合分析判断区内北东、北西向构造交汇夹角的南北引张区是热液活动的良好通道和热储场所,为地热资源开发利用提供参考。Huizhou of Guangdong Province is located in the eastern margin of South China Plate and belongs to the fault fold belt along the southeast coast.According to the results of field geological investigation,the geological structure characteristics and tectonic evolution law of Huangshadong geothermal field and its surrounding area are summarized.The study area has experienced multiple stages of tectonic movement,and basically formed a"checkerboard type"fault structure pattern group mainly oriented to the northeast and northwest.The NE and NW trending structures are important geothermal-controlling structures,which have strong correlation with the geothermal distribution in the region.It is concluded by comprehensive analysis that the north-south expansion area at the intersection Angle of the NE and NW trending structures in the region is a good channel for hydrothermal activities and a heat storage site,which provides a reference for the development and utilization of geothermal resources.
