摘要
威海市草庙子镇洪水岚汤温泉是低温热水型地热田,位于苏鲁造山带(Ⅰ)胶南隆起(Ⅱ)乳山-威海凸起的东部。热储位于印支期花岗岩构造破碎带内,受NW,NE向断裂构造控制,呈点状、带状分布,洪水岚汤位于2个断裂构造交会处,出露标高66.83 m,平均水温71℃。根据流体化学特征分析,洪水岚汤温泉热水来源主要是大气降水,水化学类型按舒卡列夫法分类属HCO3-.SO42--Na+型热泉,氟、偏硅酸含量较高,含有多种微量元素和放射性元素。
Hongshuilantang geothermal spring in Caomiaozi town of Weihai city is low temperature type geothermal field.It located in the east part of Rushan-Weihai uplift of Jiaonan uplift（Ⅱ） in Sulu orogen belt（Ⅰ）.Geothermal reservoir located in the fracture zone of Indosinian grantites,controlled by faults with the trend of NW and NE,and distributed in point and ribbon type.Hongshuilantang geothermal spring located in the intersection of two faults.Its exposed elevation is 66.83m and average water temperature is 71 ℃.According to the analysis of chemical characteristics of fluid,the hot water source of Hongshuilantang geothermal spring is precipitation,water chemistry types are HCO-3,SO2-4-and Na＋ thermal springs according to the classification method by Shukaliefu.Fluoride and silicic acid contents are high,and containing many trace elements and radioactive elements.
