新疆沙湾县南山温泉地热资源地质特征

Geological Features of Geothermal Resources in the Nanshan Hot Spring in Shawan,Xinjiang

在野外实地调查基础上,通过分析研究新疆沙湾县南山温泉的热源通道、入渗通道,讨论其成因机理和开发利用前景。研究结果表明:该地热资源受断裂构造控制,出露温度为31.7-50.6℃,以深部区域酸性岩体为热源,以斯勒格达坂张扭性断裂和张性导水断裂为导热、导水通道,多条断裂(裂隙)带控制着沙湾县基底构造及地热资源展布。在充分收集区域地质、水文、物探及地热资料基础上,通过对断裂构造特征研究,分析温泉县地热资源的形成背景、赋存条件、分布规律,为进一步研究、勘探及开发地热资源提供依据。

This paper deals with geological features,distribution,occurrence,genetic mechanism and exploitation of geothermal resources in the Nanshan hot spring in Shawan,Xinjiang.The study indicates that the geothermal resources are controlled by fault structure.The temperature is 31.7-50.6℃,acidic rock mass in the depth is the heat source.The Silegedaban tensional fracture is the heat-conductive and water-conductive channel.
