摘要
作为鉴定矿物岩石性质的主要方法,岩矿鉴定法主要通过偏光显微镜测定岩石矿物得到其相关光学参数。但对于隐晶质矿物与部分相似矿物亚类间识别的精确程度无法确保鉴定有效性。本文以岩矿鉴定法为切入点分析其鉴定流程,就提出具体的金矿床矿石特征分析要点进行深入探究,为相关人员提高鉴定有效性。
As the main method to identify the properties of mineral rocks, the rock mineral identification method is mainly obtained by polarizing microscope to determine the related optical parameters of rock minerals. However, the accuracy of the recognition between the crypto minerals and the subclasses of some similar minerals can not ensure the validity of the identification. Taking the identification method of rock and mineral as the breakthrough point, this paper analyzes the identification process, and puts forward the specific points for analyzing the characteristics of gold ore, so as to improve the effectiveness of identification for relevant personnel.
