| 中文摘要: |
| 成矿年代一直是矿床学研究的热点问题。矿床形成时代的确定对认识矿床成因、成矿事件与其他异常事件的耦合关系认识、以及对找矿勘探均具有重要的理论及实际意义。文章系统阐述了国内外有关矿床同位素定年方面的最新进展和古地磁法、地质体定年法的基本原理,并对常用同位素定年法的适用性和局限性进行了评述。 |
| 英文摘要: |
| 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. |
