摘要
实验证实，岩块在高温高压受力变形后，其矿物中的元素将发生迁移和变化，在相同条件下，同一矿物中的不同元素或相同元素在不同矿物中具有不同的迁移和变化规律。实验结果说明，就许多内生金属矿床成矿作用而言，构造及构造变形不仅为成矿热液的运移、沉淀提供场所，而且在某种程度上能促使成矿元素的活化、分异甚至富集。
There are migration and accumulation of ore forming elements in rocks deformed under high temperature and pressure.The results of the experiment shows that this differs for different elements in the same mineral and for same element in different minerals under the same condition.And it is found that the structures of the deformed rocks not only provide the passageway and space of deposition for the ore forming fluid,but also play an important role in the activation and differentiation of the ore forming elements at the initial mineralization.
