矿床地球化学近十年若干研究进展

Some Advances in Ore Deposit Geochemistry in Last Decade

矿床地球化学的主要任务是研究各种地质作用过程中矿床形成的地球化学问题,重点包括成矿元素的地球化学行为、成矿元素的源-运-储过程和矿床形成的驱动机制等。矿产资源勘查已越来越依赖于成矿新理论的指导和找矿新技术新方法的应用。因此,近10多年来,探索成矿新理论一直是地质学家们的不懈追求,矿床地球化学研究取得明显进展。本文扼要论述了其中的几个方面,包括大陆动力学与成矿关系、成矿流体地球化学、矿床同位素地球化学、成矿年代学和分散元素成矿作用等方面的某些研究进展。

Ore deposit geochemistry mainly deals with the geochemical issues related to the formation of ore deposits in various geological emvironments Understanding geochemical behaviors of ore-forming elements,metallogenic processes-and the driving mechanism for ore formation has been the focus of intensive research effort over the last decade.This paper presents a status update of research on the relationship between continental dynamics and met-allogenesis,ore-forming fluid geochemistry,isotope geochemistry of ore deposit,metallogenic geochronology and mineralization of dispersed elements.
