湖南岳阳公田地热资源地质特征及控热构造

Geological features and thermal control structure of geothermal resourcesin Gongtian, Yueyang City, Hunan Province

在综合勘查及水文测试资料的基础上,分析了湖南公田地热资源的地质特征及控热构造。结果表明:研究区公田断裂破碎带赋存的构造裂隙水为区内的地下热水资源,水量较丰富;公田地热资源主要来自地壳深部的热传导,次为幕阜山岩体的岩浆余热传导;公田断裂(F 1)及北西向断裂(F 2)是区内控热导水构造。

On the basis of comprehensive survey and hydrological test data,the geological features and thermal control structure of geothermal resources were analyzed in Gongtian area,Hunan.The results showed that the abundant structural fissure water in the Gongtian fracture zone was the underground hot water resource of the study area.The geothermal resources mainly came from the heat conduction of the deep crust and the magma residual heat conduction of Mufushan rock mass.Gongtian fault(F 1)and NW fault(F 2)were the internal heat-controlling and water-conducting structures.
