广东从化新温泉地热水地质特征及成因分析

The geological features and genesis analysis of Conghua new hot spring geothermal water in Guangdong

广东从化新温泉地热水受控于广从断裂破碎带及深循环作用,区域地质条件良好。广从新温泉地热水的热水类型为断裂-深循环型地热水,其成因主要为大气降水入渗补给→地下水深循环加热形成地热水→向上运移以温泉形式出露;地热水主要分布于控热构造破碎带内或者受控热构造影响较为明显的区域,广从断裂破碎带是广东从化新温泉热水点的控热和导热构造。广东从化地区构造极为发育,降水量充沛,深部地热水热水补给来源良好,为温泉地热水的持续性开发利用奠定了基础。

The Conghua new hot spring geothermal water in Guangdong Province is controlled by Guangcong fault zone and deep circulation,and the regional geological conditions are good.The hot water type of Conghua new hot spring geothermal water is fault-deep circulation geothermal water,The main formation process of which is infiltration of atmospheric precipitation recharging,underground water heated by depth circulation becoming geothermal water,upward migration and emergence in the form of hot spring.Geothermal water is mainly distributed in the fracture zone of thermal control structure or the area with obvious influence of controlled thermal structure,as Guangdong-Conghua fracture zone is the thermal control and conduct structure of Conghua new hot spring geothermal water.Conghua area in Guangdong Province has well developed structure,abundant precipitation,and good supply of deep geothermal water and hot water,laying a foundation for the sustainable development and utilization of hot spring geothermal water.
