甘肃省肃南县塔里干沟铁铜矿地质特征及找矿标志

Geological characteristics and prospecting Iron-copper deposits in Gansu province Sunan County tower ditch

塔里干沟铁铜矿是甘肃北祁连西段镜铁山外围勘查成果之一,为以菱铁矿矿石为主的沉积变质型铁矿。矿体分布在长城系桦树沟组滨-浅海相浅变质细碎屑岩建造中,并严格受其控制。本文分析了塔里干沟铁、铜矿的成矿地质背景,系统总结了矿床成矿条件、矿体特征等,建立了成矿模式,总结了找矿标志,以期能为今后在该地区寻找同类型矿床提供帮助。

The tower is Gansu North West of Qilian Gangou iron ore of Tieshan iron ore iron ore prospecting results mirror periphery, is of sedimentary metamorphic iron ore dominated by siderite. The ore bodies are distributed in the construction of the waterfront shallow metamorphic fine clastic rocks in the Betula Shilou formation of the the Great Wall system, and are strictly controlled by them. This paper analyzes the geological background of the iron tower ditch are summarized systematically, metallogenic conditions, ore body characteristics, metallogenic model is established, summarized the prospecting, in order to find the same type of deposit to provide assistance in the area in the future.
