前言据有关资料记载,一九六○年以前国内外已发现的铂族矿物仅有六种左右。由于电子探针 X 射线显微分析这一新的测试方法的应用,到一九七二年已发现铂族矿物达七十四种;另外还有六十五种铂族矿物尚未定名。可见现代精密分析技术的采用,对铂族矿物详细研究和分类都有重大的意义。笔者曾从事过青海北祁连山某地砂铂矿床的重砂鉴定工作,但因受当时鉴定条件的限制,很长时间未能对该矿床的铂族矿物做出确切的鉴定与分类。后来在贵阳地化所等
According to the relevant information, there are only about six types of platinum group minerals discovered at home and abroad before 1960. Due to the application of this new test method for electron probe X-ray microanalysis, 74 seventy-four platinum group minerals have been discovered by 1972; in addition, there are another 65 platinum group minerals not yet named. Shows the use of modern sophisticated analytical techniques, platinum group minerals in detail the study and classification are of great significance. Although I was once engaged in the identification of heavy sand in a sand-platinum deposit in a certain place in Qilian Mountains of Qinghai Province, due to the restriction of the identification conditions at that time, I have not been able to identify and classify the platinum group minerals of this deposit for a long time. Later in Guiyang and so on
