小秦岭金矿是我国的主要黄金产地之一,近年来,随着各项研究工作的日趋深入,矿床远景不断扩大。本文从自然金的化学成分、粒度、形态及赋存状态等方面研究和探讨了陕西小秦岭金矿中金的标型特征。并对本区的主要载金矿物黄铁矿作了概述。总结出了自然金的成色与成矿温度、矿化阶段和矿床形成深度等之间的一般规律。同时指出,对自然金成色的深入研究,可以为本区含金石英脉脉体评价及矿床成因探讨提供依据。
Xiaoqinling gold mine is one of the main gold producing areas in China. In recent years, with the deepening of various research work, the prospect of the deposit has been expanding. In this paper, the chemical composition, grain size, morphology and occurrence status of natural gold were studied and discussed in this paper. The main gold-bearing pyrite in the area is summarized. Summarized the formation of natural gold and metal forming temperature, mineralization stage and the depth of the formation of the general rule. At the same time, it is pointed out that an in-depth study of the natural gold color can provide a basis for the evaluation of gold-bearing quartz veins and the genesis of the deposit in this area.
