| 摘 要： | 三维地质模型集成了大量的地质、地球物理、地球化学、遥感及钻孔数据,不仅具有直观可视化以及人工交互功能,而且能够反应地下深部构造信息,为矿产勘查提供强有力的依据.本文结合新疆哈密红海VMS型铜(锌)矿床,利用实测数据和解译数据在Gocad平台创建了三维地质模型.三维结构模型说明了收集的数据、建模的方法及流程,反应了矿体形态及地质体之间的主体关系,三维栅格模型具有的多信息属性显示了矿体中Cu品位的分布变化情况,Kriging法计算了黄土坡块段矿体资源量,并为勘探圈定了一个新的靶区. |
| 关 键 词： | 三维地质模型 红海 Gocad 勘探靶区 |

| Abstract: | Abstract: A three-dimensional geological model integrates a large amount of geological, geophysical, geochemical, remote sensing and borehole data to achieve direct visualization and interactive interpretation, and to assist understanding of deep geological structures, providing foundation for mineral exploration. This work utilized measured and interpreted data to construct a 3D geological model for the Honghai VMS copper (zinc) deposit in Hami, Xinjiang with the Gocad software. The 3D structure model was built to demonstrate the collected data, method and workflow of modeling, and describe the ore body shape and main relationship of geologic bodies in the study area. The 3D grid model with many kinds of attributes shows the spatial distribution and variation of copper ore grade, based on which ore body reserves were calculated using the Kriging algorithm, and a new target area for exploration was determined. |
