| Abstract: | Ore-forming age has long been one of the key problems of the research on economic geology. The determination of the ore-forming age is of great significance both in theory and in practice, which is helpful to the understanding of the origin of an ore deposit and the coupling relationship between mineralization events and other abnormal geological events and also to the exploration of deposits. This paper discusses systematically the newly made progress in isotopic geochronology of ore deposits both at home and abroad, as well as the fundamental principle of fission-track and paleomagnetic dating. In addition, various dating methods are described in terms of their applicability and limitation. And finally, the dating methods for ore deposit are reviewed. |
