摘要
二甲金矿是新近发现的构造蚀变岩(硅化-糜棱岩)型金矿.本文分析了糜棱岩(石英)含矿性的构造动力机制,并讨论了石英的红外和顺磁谱学特征,结果表明,恢复作用和动态重结晶作用对金成矿最有利;含金性不同的石英,其谱学特征存在着明显的差异,这些差异可作为评价本区石英含矿性的标志.
Erjia gold deposit is of altered rock (silicification-mylonite) type discovered in recent years. This paper deals with the tectonic kinetics of ore-bearing mylonite (quartz) and the characteristics of IR and EPR spectra for quartz from this area through which the following conclusions have been reached: 1) restoration and dynamic recrystallization is of most benefit to gold mineralization; 2) quartz with different content of gold is much different in characteristics of IR and EPR spectra. These distinctions can be used as indications in propecting quartz from this area.
