成矿系统理论视角下的呵叻高原钾盐矿床研究现状及展望

Discussion on research status and prospects of the Khorat Plateau potash deposit on the basis of the metallogenic system theory

成矿系统理论将矿床视为动态演化的自然系统,矿床从发生、形成到发展的整体演变过程及其控制机制是该理论的研究核心,“源、运、储、变、保”是该理论剖析矿床成因的五个基本着眼点。东南亚呵叻高原超大型钾盐矿床作为我国海外钾肥生产基地的标志性成功案例,其成矿系统研究不仅关乎该矿床成因认识的深度及其开发利用的广度,同时对中国东特提斯域内找钾工作具有重要指导作用。本文拟基于前人的研究成果,借助成矿系统理论,运用动态的整体思维对呵叻高原钾盐矿床成因研究现状进行梳理,探讨时间维度下呵叻高原钾盐矿床“源、运、储、变、保”成矿要素的表现特征及存在的科学问题,初步提出固体可溶性钾盐矿床成矿系统的研究思路构架,以期为全球钾盐矿床深入研究提供一定借鉴。

The metallogenic system theory regards ore deposit as a natural system of dynamic evolution.The overall evolution process of ore deposit from occurrence,formation,to development and its control mechanism are the core of this theory.“Source,migration,storage,transformation,and protection”are the five basic points for this theory to analyze the genesis of ore deposit.The super-huge potash deposit in the Khorat Plateau in Southeast Asia is a landmark successful case of China’s overseas potash fertilizer production base.The systematic study of metallogenic mechanism is not only related to understanding of the genetic process of the deposit and its development and utilization,but also plays an important guiding role in the prospecting of potash in the eastern Tethys domain of China.Based on the previous researches and the metallogenic system theory,the study will sort out the research status of“source,migration,storage,transformation,and preservation”metallogenic factors of the Khorat Plateau potash deposit,and discuss its scientific problems in the time dimension.Moreover,the study will preliminarily propose the research framework of the metallogenic system of solid soluble potash deposit,in order to provide a certain reference for the in-depth research on global potash deposits.
