元素共生分异机制的研究现状和趋势——以黔西南微细浸染型金矿区为例

Actuality and Trend in Study about Mechanisms of Elemental Paragenesisand Separation as Exemplified by Fine-Disseminated Gold Deposits in Southwest Guizhou Province

元素共生分异现象在矿床中是普遍存在的。认识和查明元素的共生分异特征和形成机制 ,对丰富成矿理论和指导找矿勘探均具有重要意义。以黔西南微细浸染型金矿区为例 ,对元素共生分异机制的研究现状和存在问题进行了评述。在此基础上 ,肯定了成矿流体地球化学在元素共生分异机制研究中的地位和作用。从成矿流体地球化学研究入手 ,在查明成矿流体来源及时空演化规律的基础上 ,结合矿床地球化学、成矿实验及成矿过程的计算机模拟研究 ,深入研究成矿流体中成矿元素的来源、活化迁移条件及沉淀富集过程的共性及差异 。

The phenomenon of elemental paragensis and separation in deposits is ubiquitous. To understand and find out character and mechanism of elemental paragenesis and separation has important significance in both enriching ore forming theory and directing exploration. The actuality and shortage in study about mechanisms of elemental paragenesis and separation as exemplified by fine disseminated gold deposits in Southwest Guizhou Province have been reviewed in this paper. On the above base,the status and function of fluid geochemistry in studying mechanisms of elemental paragenesis and separation are affirmed . According to the the study of ore deposit geochemistry, ore forming experiment and computer simulation of the ore forming process , it is the key to find the difference and commonness of the source ,movement and deposition of elements in ore forming solution.
