摘要
济南市平阴县玫瑰镇大孙庄已发现两眼地热氡泉井,地热流体中氡含量高达332.6~625.7 Bq/L,属于稀缺的天然理疗热矿水资源。采用土壤面积测氡、土壤剖面测氡、可控源音频大地电磁法(CSAMT)测量、水氡测试等方法,研究其形成机理。通过分析氡的物源条件、空间条件、动力条件,结合地热田的地质条件、水文地质条件、构造条件、水化学特征,建立了大孙庄地热氡泉形成机理模型,为在具有类似地质背景条件的地区勘查开发地热氡泉提供借鉴。
Two geothermal radon spring wells have been found in Dasunzhuang area in Meigui town in Pingyin county in Ji'nan city.The radon content in geothermal fluid is 332.6~625.7Bq/L,which is a rare natural physiotherapy hot mineral water resource.Based on extensive collection of previous research data,its formation mechanism has been studied by means of radon measurement in soil area,radon measurement in soil profile,controllable source audio frequency magnetotelluric method(CSAMT)measurement,and radon measurement in water.By analyzing the material source conditions,spatial conditions and dynamic conditions of radon,combining with geological conditions,hydrogeological conditions,structural conditions and hydrochemical characteristics of geothermal field,the formation mechanism model of Dasunzhuang geothermal radon spring has been established.It will provide some references for the exploration and development of geothermal radon spring in similar geological background conditions.
