探讨成矿溶液酸度变化的规律和原因,是地球化学实验工作者的重要任务之一。概括了许多地质研究者的观察,将内生成矿溶液酸度变化划分为四个阶段,即早期碱性,中期酸性,后期碱性,终期中性。为了进一步阐明这个规律,柯氏提出了“酸性波”的假说。由于缺乏足够的实验研究,使得这个假说一直停留在一般原理上的论述。对KCl- It is one of the important tasks for geochemical experiment workers to explore the law and reason of acidity variation of ore-forming solution. This paper summarizes the observations made by many geologists and divides the acidity changes of endogenic mineral deposits into four stages, that is, early alkaline, medium-term acidity, late alkaline, and final neutrality. In order to clarify this law further, Köscher put forward the hypothesis of “acidic wave”. Due to the lack of sufficient experimental research, this hypothesis has been stuck in the general theory of discourse. KCl-
