As the only geothermal mineral resources of the new energy in the world, due to geothermal resource owning hot, mineral and water as a whole and with a clean, cheap, easily exploited characteristics, it obtains a wide attention by the world. From the begin-ning of the background of the regional geological structure of Wulongkou geothermal zone in Jiyuan, by analyzing the chemical composi-tion and chemical characteristics of the thermal mineral water and studying the cause of thermal mineral water, the following conclusions are drawn:the hot mineral water of Wulongkou geothermal area is divided into three types according to different temperatures including cold water (less than 25℃), warm water (25~40℃), and warm hot water (more than 40℃);the hot mineral water of Wulongkou geothermal area has three characteristics such as the degree of mineralization increases with the increase of temperature, it contains high levels of fluorine and silicon dioxide, and heavy metals and other harmful substances content are higher;a series of reactions between the geothermal water and the surrounding rock will form different water quality types of hot mineral water.%地热资源作为新能源中唯一的矿藏资源,集热、矿、水为一体,具有洁净、廉价、易开采等特点,受到世界各国的广泛重视.本文从济源市五龙口地热区的区域地质构造背景入手,通过分析热矿水中化学组分和化学特征,研究热矿水的成因.得出如下主要结论:五龙口地热区热矿水因温度的不同可分为3类,即冷水(小于25 ℃)、温水(25~40 ℃)、温热水(大于40 ℃);五龙口地热区热矿水有三大特征,分别是:矿化度随着温度的升高而增高,氟和偏硅酸的含量高,重金属等有害物质含量较高;地热水与围岩发生一系列反应从而形成不同水质类型的热矿水.
