大同盆地后所凹陷山阴县安祥寺一带地热地质条件分析

Analysis of geothermal geological conditions in the Anxiangsi area of Shanyin County located in Housuo depression in Datong Basin

大同盆地为新生代断陷盆地,具有较优越的地热地质条件。山阴县安祥寺位于大同盆地桑干河新裂陷后所凹陷西南段构造单元内,本文研究了山阴县安祥寺一带的地热地质条件,认为:山阴县安祥寺一带受断裂构造控制,断裂带可作为良好的水循环通道,形成深循环对流模型;第四系和新近系为区域内良好的保温盖层。综合评价认为安祥寺地热田属隐伏型低温地热田,具有经济开发价值。

The Datong Basin is a Cenozoic faulted basin with excellent geothermal geological conditions.This paper analyzes the geothermal geological conditions of Anxiangsi area in Shanyin County,which is located in the southwest tectonic unit of the Housuo depression in the new Sangganhe rift of Datong Basin.The results show that the Anxiangsi area is controlled by fault structure,and the fault zone can serve as an effective water circulation channel,leading to the formation of a deep circulation convection model.Additionally,the quaternary and Neogene system act as effective thermal insulation covers in the region.Overall,the Anxiangsi geothermal field is a concealed low-temperature geothermal field with economic development potential.
