| 摘 要： | 在宏观和微观地质特征研究基础上,运用硅同位素动力学分馏原理,结合硅质阴极发光分析,论证了微细浸染型金矿的成矿硅质、矿质和流体主要直接来源于上地幔分异或深部循环的超临界流体,并认为这种深部因素可能对形成大型和超大型矿床发挥了重要作用.这对该类型金矿的成因研究及找矿开辟了新的思路.

| Abstract: | On the basis of the study on macro and micro geologic features of micro disseminated gold deposits in China,applying silicon isotope dynamic fractionation principle combined with siliceous cathodoluminescence,the authors hold that mineralizing silica,ore forming substances and fluid origin directly from upper mantle differentiation or from deep circulating supercritical fluid This kind of deep factors may play an important role in forming large and superlarge deposits The conclusions, at the same time,may bring forth a promising thought in the studying on genesis and prospecting for this type of gold deposits |
