摘要
位于青藏高原东部的青海省同仁地区,构造活动强烈,地热地质条件优越,出露有水温46. 6℃的曲库乎温泉和82. 2℃的兰采温泉。高精度地面磁法资料显示,同仁县东侧的加吾乡地区,新近系地层下隐伏有高放射性的侵入岩体。通过对区域热构造背景条件的分析,结合可控源音频大地电磁测深法对断层的解译发现,该岩体系受区域带状热源所在的瓦里贡山-多禾茂走滑挤隆构造带控制而侵入就位的。综合分析认为,同仁县加吾乡地区发育有断层传导热和放射性热源共同供热的干热岩资源,系干热岩资源进一步勘查的有利地段。
Tongren area of Qinghai Province in the eastern part of the Qinghai Tibet Plateau has strong tectonic activities and superior geothermal conditions.The Qukuhu hot spring with water temperature of 46.6 ℃ and Lancai hot spring of 82.2 ℃ are exposed.High-precision ground magnetic data showed that high-radioactive intrusive rocks were hidden beneath the Neogene strata in Jiawu on the east of Tongren County.Based on the analysis of the regional thermal tectonic condition and the interpretation of the fault by the controlled source audio-frequency magnetotelluric(CSAMT)method,it was found that the rock system was affected by the regional belt heat source in the Waligong-Duohemao strike-uplift tectonic belt.According to the comprehensive analysis,the dry-hot rock resources co-heating with fault condition heat and radioactive heat source were developed in Jiawu,Tongren Country,which is a favorable section for the further exploration of dry hot rock resources.
