摘要
水是化学元素迁移的一种主要营力，其溶解物质影响水体的pH值高低，pH值又控制着元素迁移的习性。水中化学元素的含量受景观条件的制约，但矿化类型是元素组合的决定因素。本文在两个地区的试验研究结果论证了水化学方法在气候潮湿、地表污染严重地区测量结果在指示找矿方面的可靠性，同时也证明了在半干旱的风成沙覆盖区进行找矿的作用。经研究总结，确定不同矿化类型水化学指标，肯定了方法的效果，并发现了找矿的有利地段。
Abstract
Water is a major agent for the migration of chemical elements, the substances dissolved in it affect its pH value, and its pH value, in turn, affects the behavior of element migration. The contents of chemical elements in water are governed by landscape conditions, but the mineralization type is a decisive factor of mineral association. With experimental results of two areas as examples, this paper demonstrates the reliability of the hydrochemical method in guiding ore prospecting work in areas with humid climate and heavy surface contamination, and also indicates its active role in ore-prospecting work of semiarid areas covered by eolian sand. Through study and summarization, hydrochemical indices for different mineraliza tion types have been determined, and the effectiveness of this method has been confirmed, together with the discovery of some promising areas for ore prospecting.
