Abstract Water is a major agent for the migration of chemical elements, the substances dissolved in it affect its pHvalue, and its pHvalue, 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.
