摘要
青海省格尔木市驼路沟钴 (金 )矿床是东昆仑地区新近发现的、国内外罕见的矿床新类型。笔者通过研究首次认为该矿床形成于晚海西—印支—燕山期 ,为与富钠火山岩有关的层控 -改造型独立钴 (金 )矿床 ,原富钠的中酸性火山岩中Co、Au初始富集 。
The Tuolugou cobalt (gold) deposit was first discoveried recently in East-KunLun district, Germu County, QingHai province. It is a new type of cobalt deposit in the world. We study this deposit and suggest that it was formed in late Variscian to Yinzhi-Yanshan epoch and that it is a independent strata-bound and remolding type cobalt deposit related to sodium volcanic rocks . Co, Au was first accumulated in this sodium-bearing intermediate-acid volcanic rocks and became cobalt (gold) deposit by the later kinetic metamorphism.
