摘　　要：地热属于清洁的可再生能源,天津地区蕴藏着丰富的地热资源。As、B、Be、Bi、Hg、Sb等可以作为岩石、土壤、水系沉积物测量的重要指标,在土壤地球化学测量中可以使用这些元素来进行地热田异常调查。本文利用天津地区多目标地球化学土壤调查数据,分析了天津地区地热田异常区内表层和深层土壤中As、B、Be、Bi、Hg、Sb的地球化学异常,研究认为土壤中As、B、Be、Bi、Hg、Sb的地球化学异常对天津地区地热田异常具有很好的指示作用,可以为今后预测地热资源的空间分布和规划开发提供重要依据。Geothermal belongs to clean and renewable energy,and there is abundant geothermal resources in Tianjin area. As、B、Be、Bi、Hg、Sb can be used as important indexs of rock、soil、stream sediment survey,and we can use these elements to investigate geothermal anomaly in the soil geochemical survey. This paper analysis geochemical anomalies of As、B、Be、Bi、Hg、Sb in surface and deep soil in thegeothermal field in Tianjin area by soil survey datas of multi target geochemical of Tianjin area. Researching suggests that geochemical anomaly of As、B、Be、Bi、Hg、Sb in soil have very good indicative function on the abnormal geothermal field in Tianjin area,and can provide an important basis for distribution and development of geothermal resources in the future.
