珠江三角洲地热田远景的构造环境分析

THE ANALYSES OF STRUCTURE ENVIRONMENT OF GEOTHERMAL POTENTIAL AREAS IN PEARL RIVER DELTA

本文通过时区域地质、地温场、活动断裂、新生代火山活动、断块构造、地壳形变、地震活动、构造应力场等与温泉分布关系的分析，认为珠江三角洲并非少有温泉或地热田。可是具有良好地热田远景的区域。就地热田远景区而言，南部地区较北部地区好，西部地区较东部地区好。由于地温较高地区构造活动性较强，因此也是灾害性地质现象较集中发生的部位。

With the analyses of the relations between the hot-spring and the regional gelogy, geothermal field, active faults, Cenozoic volcano activity, fault-block, crustal disformation, seismic activity,stress field,etc. it is considered that here are not rare hot-springs or geothermal areas, but are some of better geothermal potential areas in Pearl River Delta. The geothermal potential.in the south region is better than that in the north region, and better in the west region than in the east region. Because of the stronger structural activity in the bigher geothermal area, disaster-geological phenomena maytake place here.
