摘要
通过对粤西深大断裂(即信宜-廉江深大断裂带区域)温泉地球化学特征等研究,揭示其水化学组分主要为硅酸盐矿物的溶解控制,Na-K-Mg图解显示研究区内热泉水岩作用处于不平衡状态,另外还估算了地热水的热储温度为63.2-122.5℃及循环深度为1453-3430 m.该成果可为进一步探讨地热水与深大断裂之间的联系及水文地质条件、地质构造及地热资源开发等提供依据.
Through the study of the hydrogeochemical characteristics of the hot springs in the deep fault of the western Guangdong(namely Xinyi-Lianjiang deep fault zone), it was revealed that the water chemical components were mainly the dissolution control of silicate minerals, and the Na-K-Mg diagram showed that the hot spring water-rocks interactions were in an unbalanced state. Meanwhile, the thermal storage temperature was estimated to be between 63.2-122.5 ℃, and the circulation depth was in the range of 1453-3430 m. Our results could provide a basis for further exploration of the relationship between geothermal water and deep faults, as well as shallow geological structures, hydrogeological conditions, and geothermal resource development.
