摘要
将三维可视化技术应用于大比例尺矿产资源评价是地学领域一项热点研究课题。通过建立各种模型,使地质工作者能够全视角地认知工作区的地形、地层、构造和岩体等地质体间相互关系,能够将各种地质体、地球化学异常、地球物理异常、蚀变带、反演出的地质体以及它们之间的相互关系形象直观地反映出来。通过对空间体单元进行赋值,利用地质统计技术对这些空间数据进行计算,可以较科学地实现定位预测及定量预测的目的。该三维预测方法的应用,为大比例尺矿产预测,尤其是矿区深部及外围预测,提供了一种新的工作思路和手段,具有较高的推广与应用价值。
It's a hot research project that puts three-dimensional visualization Technology into geologic area to do large scale mineral assessment. The various established modes can give geologists a panoramic view of the relations among terrains, formations, constructions, ore rocks and other geological entities. They can also vividly and directly reflect the relationships between geologic bodies, geochemical anomalies, geophysical anomalies, inversed geologic bodies and altered geologic bodies . Through value assignment to the space body units, geologists can scientifically calculate these space data and make location prognosis and quantitative assessment. This method provide a new way and a new idea for large-scale nfineral assessment and is worth popularizing and applying.
