格尔木市扎日玛日那西铁矿矿床地质特征及找矿前景分析

Geological Characteristics and Prospect Analysis of Naxi Iron Deposit in Zharimarina Area of Geermu City

摘要:

格尔木市扎日玛日那西铁矿属小型铁多金属矿床，矿区内目前已探测出13条铁矿体和4条锌矿体。通过对矿区内矿床地质特征、矿石特征、磁异常特征、控矿因素等进行研究分析，认为该矿床为矽卡岩型矿床， NW向断裂和接触带是重要的导矿、控矿因素，铁矾帽、磁异常、矽卡岩、颜色为重要的找矿标志，该矿床具有较好的找矿前景。

Abstract:

Naxi iron deposit in Zharimarina area belongs to small iron polymetallic deposit. 13 iron orebodies and 4 zinc orebodies have been detected in mining area currently. In this paper, through research and analysis on regional geological characteristics, ore characteristics, magnetic anomaly characteristics and ore controlling factors, it is regarded that this deposit is a skarn deposit. Faults with the trend of NW and the contact zones are important ore prospecting indicators for ore-guiding, ore controlling factors, iron alum cap, magnetic anomaly, skarn and color. This deposit has good ore prospecting future.
