Mineral deposit is the product of the geologic evolution of Earth's history. Each ore deposit underwent its own formation process and postore change and preservation history. Thus genesis and postore changepreservation are two primary aspects of mineral deposit research. Employing the view of the historical evolution to ascertain the whole process of formationchangepreservation of ore deposit is not only conducive to enhancing the level of mineral deposit theory, but also to the demands for mineral exploration. The authors proposed three levels in mineral deposit research: ① single ore deposit formationchangepreservation, ② regional metallogenic evolution, and ③ global metallogenic evolution. Single ore deposit research and regional metallogenic evolution should receive equal attention. Restoring metallogenic history and investigating temporalspatial metallogenic regularities of mineral deposits to give the guide to deposit exploration has been the main theme for mineral research; while the postore change and preservation, as another important aspect of the mineral deposit geology, should arise enough attention and strengthen the research on it.
