通常将活动地热田作为浅成低温热液金银矿成矿体系的模型。通过详细调查含有沸腾流体的地热井中不同深度上的沉淀物,对这一模型进行了研究。本文提供的成果表明,墨西哥赛罗普列托地区M-53井中Au、Ag、Cu,Pb和Zn的含量及其分布特征可以与在浅成低温热液脉状工业矿床中发现的结果相比较,其金属含量峰值位于流体产出带(即含水层或开采层—译注)或其附近。该深度正与井中气体开始发生分离或急骤蒸发的深度相吻合,这
The active geothermal field is usually used as a model for the epithermal gold-silver mineralization system. This model was investigated by detailed investigation of sediments at different depths in geothermal wells containing boiling fluids. The results provided in this paper show that the content and distribution of Au, Ag, Cu, Pb and Zn in Well M-53 in the Sere Prieto area of Mexico can be compared with those found in shallow-low-temperature hydrothermal vein-like industrial deposits With its metal content peak at or near the fluid-producing zone (ie, aquifer or mining zone). This depth is coinciding with the depth at which gas in the well begins to separate or flash evaporate
