| 中文摘要: |
| 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。 |
| 英文摘要: |
| Geotherm is one kind of clean and renewable energy. There are abundant geothermal resources in the Tianjin area. Elements, such as As, B, Be, Bi, Hg, and Sb can be used as important indexes for surveys of rock, soil, and stream sediments, which are objects of investigations of geothermal anomalies. This paper analyzes the geochemical anomalies of these elements in the surface and deep soil in the geothermal fields of the Tianjin area by using survey data. Our research suggests that the geochemical anomalies of these elements in soil are very good indicative signatures for the geothermal fields in the Tianjin area, and can provide important evidence for distribution prediction and development planning of geothermal resources in the future. |
