摘要:
基于马蹄沟金矿已有的勘查工程数据和研究成果,利用Surpac软件平台建立了马蹄沟金矿区三维可视化地学模型,三维直观且定量地展现了马蹄沟金矿地形、地层、构造和矿化域基本情况。综合研究了该矿区金矿化的空间分布规律,认为马蹄沟金矿体主要沿NW-SE向展布延伸,罗汉寺—瓦窑上韧脆性逆冲推覆断层(F9)及其派生和演化构造是本矿区主要控矿构造。随着高程由高到低变化,矿化强度有减弱趋势,且呈现出不连续特征;矿化有向深部延伸的趋势;1 450~1 550 m中段是该矿成矿有利区段。通过对马蹄沟金矿化分布规律和矿化强度变化特征进行研究,结合矿化与构造之间的关系,在矿区圈定出2处找矿预测靶区。研究结果为该矿区下一步找矿勘查工作提供了依据。
