北祁连地区在历史上曾大规模开采过砂金,在采砂金过程中发现一种极难与金机械分离的矿物(俗称钢砂),经鉴定分析确定是自然铂族矿物.解放后,先后有几个兄弟队在这一带进行过砂矿普查勘探工作.我队于一九六七年开始,在北祁连地区以砂铂矿为主进行了较系统的普查找矿工作,并积累了一定的地质资料.遵循毛主席关于“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的伟大教导,在综合以往地质资料的基础上,对北祁连砂铂矿成矿规律进行初步总结.鉴于水平所限,谬
In the North Qilian area, large-scale mining of gold has been carried out in history. During the process of gold mining, a type of mineral (commonly known as grit) that is extremely hard to be separated from the gold is found and identified as a natural platinum group mineral after identification and analysis. There have been several brothers in this area for sand census exploration work.Our team started in 1967, mainly in northern Qilian sand and platinum ore carried out a more general prospecting work, and accumulation A certain amount of geological data.According to Chairman Mao’s great teaching on “mankind should constantly sum up experience, some discovery, some invention, some creation, some progress ”, on the basis of synthesizing the geological data in the past, North Qilian sand and platinum ore metallogenic regular preliminary summary given the level of limitations, absurd
