赣南东部地热水特征及成因分析

Analysis of Characteristics and Causes of Geothermal Water in the East of Southern Jiangxi Province

赣南东部地区具有众多的地热水出露,是我国地热资源开发利用的重要区域。通过对赣南东部地区15处地热水出露特征及放射性元素进行分析,结合该区域地质构造环境,指出赣南东部地热水主要沿石城-瑞金断裂带、会昌环形构造、罗塘-丘坊断裂三条主断裂带出露,三条主断裂受构造活动形态及活动期次影响,沿其出露的地热水特征亦不相同。该地区地热水的热源主要来源于地下水深循环及放射性元素衰变。对赣南东部地热水特征分析及形成成因的揭示,可以为该地区地热水开发利用提供了理论依据。

There are many geothermal water in the east of Southern Jiangxi Province,which is an important area for the development and utilization of geothermal resources in China.The analysis of characteristics and causes of geothermal water is beneficial to geothermal water exploration.Based on the analysis of 15 geothermal waters with structure in the east of Southern Jiangxi Province,geothermal water in east of Southern Jiangxi Province mainly exposed the Shicheng-Ruijin fault zone,Huichang circular structure,Luo Tang-Qiufang fracture are revealed.The three main faults were influenced by tectonic activity patterns and active phases,The characteristics of geothermal water depended on faults.The heat source of geothermal water in this area mainly derived from underground water circulation and radioactive decay.The characteristics of geothermal water in the eastern part of Jiangxi Province and the cause of formation are discussed,which provides a theoretical basis for the development and utilization of geothermal water in this region.
