EXPERIMENTAL STUDY ON MIGRATION AND ACCUMULATION OF ORE-FORMING ELEMENTS UNDER HIGH TEMPERATURE AND PRESSURE

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.
