Abstract: Crossing between different disciplines has been the current focus of research and cross-application of their theory is of great importance.Between the forming processes of reservoirs and endogenous deposits,there are some similarities on sources of ore-forming,migration,accumulation and distribution.The cross-study between reservoirs and endogenous deposit on formation can effectively reveal the similarity between the two and then provide a theoretical basis for cross-application.In this paper,we compare the differences among sources,migration,accumulation,save,distribution,saving,and other aspects of the reservoirs and the endogenous deposits(in hydrothermal deposits for example) to find out the differences and similarities for providing some help in a more in-depth follow-up study.
