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。

Abstract:

Based on the existing exploration engineering data and research results of Matigou gold mine,a 3D visual geoscience model of Matigou gold mine area was established by using Surpac software platform.The 3D visualization geoscience model visually and quantitatively shows the basic conditions of the terrain,stratum,structure and mineralization of Matigou gold mine.The comprehensively study about the spatial distribution of gold mineralization in the mining area was conducted.It is believed that Matigou gold orebody mainly extends along the northwest-south eastward direction.The toughness and brittle thrust nappe fault (F9) and its derivative and evolutionary structures in the Luohansi-Wayaoshang are the main ore-controlling structures in the mine area.The mineralization intensity decreases from high to low,showing discontinuous characteristics.Mineralization has a tendency to extend deep,and the middle section of 1 450~1 550 m is a favorable section for mineralization of the gold mine.Through the study of the distribution law of the mineralization of Matigou gold mine and the variation characteristics of mineralization intensity and the relationship between mineralization and structure,two prospecting targets were identified in the mining area.The research results provide foundation for the next prospecting work in the mining area.

Key words: Surpac, 3D geological modeling, Matigou gold mine, solid model, block model, grade model, prospecting prediction
