摘要: 分析了采用传统地质信息表达方法存在的缺陷及开展三维立体地质填图的意义,通过对钻孔、地形和勘探线剖面等资料的综合研究,首次运用Surpac软件建立了陕南汉阴县长沟金矿床的三维可视化模型,直观地显示了地形、构造及矿体的空间展布规律。综合地质研究和三维模型特征分析结果表明:长沟金矿是一个受产于志留系区域变形变质岩中的近EW-NWW向脆—韧性剪切带DSZ3及其旁侧次级断裂破碎带控制的金矿床,含金矿化脉体主要沿S2面理分布,矿区西部的有利找矿方向应为南西区域、呈NW走向斜列的矿体沿NWW 285°~310°方向的更深部位。基于Surpac软件的三维可视化地质模型的建立和定位预测结果,对长沟金矿以及外围找矿勘查工作具有重要参考价值。
