水／岩作用实验研究表明，在低温条件下柠檬酸、草酸和酒石酸对岩石中的铁、铜都有很高的淋滤率。这表明，在表生地质作用过程中有机酸对成矿元素有很强的活化能力。实验研究同时发现，有机酸对成矿元素的活化能力受其分解温度的限制，由于大部分有机酸的分解温度都在２５０℃以下，因而有机酸对成矿元素的活化仅限于低温条件。本次研究还显示，判断一种岩石能否成为矿源层，不能简单的以其中成矿元素的含量高低作为标准，其中更关键的因素是元素在岩石中的存在形式，如果成矿元素在岩石中难以活化的形式存在，那么含量再高也无法提供成矿物质
Water / rock experiments show that citric acid, oxalic acid and tartaric acid have a high leaching rate of iron and copper in rocks at low temperature. This indicates that organic acids have a strong activation ability to metallogenic elements during the epoch-geologic process. The experimental study also found that the activation of metallogenic elements by organic acids is limited by their decomposition temperature. Since the decomposition temperature of most organic acids is below 250 ℃, the activation of metallogenic elements by organic acids is limited to low temperature conditions. The study also shows that judging whether a rock can become a source rock layer can not be simply taken as a criterion for the content of ore-forming elements. The more crucial factor is the existence of elements in the rock. If the ore- Difficult to activate the form of existence, then the high content can not provide mineralization material
