甘肃天鹿砂岩型铜矿床地质特征及成矿模式

Geological characteristics and metallogenetic model of Tianlu sandstone copper deposit in Gansu Province

文章在系统总结天鹿铜矿床地质特征的基础上,分析了成矿时代和矿床成因,并建立了成矿模式。结果表明,天鹿铜矿床赋存于中志留统泉脑沟山组杂色岩层中,其成矿物质来自陆源,主成矿期为中志留世,属沉积砂岩型铜矿床。

Based on systematic summarization of geological characteristics of the Tianlu copper deposit, this paper has analyzed its metallogenic epoch and genesis, and built up a metallogenic model. The results show that the orebearing strata occur in variegated strata of Middle Silurian Quannaogoushan Formation, that the metallogenic materials might have been derived from the land area, and the metallogenic epoch is middle Silurian.
