摘要 随着三维地质信息技术的发展,三维预测成为大比例尺深部找矿预测的重要途径和发展趋势.本文对研究区重力异常数据进行了三维反演,并用Voxler软件对反演结果进行了三维可视化呈现.对研究区已知钻孔、地质图等信息进行了数字化和投影,并以此为先验信息,选择了适当的可视化呈现方式,最后建立了能够反映区内密度分布结构的数字化模型.在此基础上,开展了部分地质解释和未知区找矿预测.结果表明:运用Voxler软件能恢复地下三维密度分布结构,以此建立的三维重力建模能够表达地质环境,并直观的对全区资料进行浏览、分析、研究.说明先验信息约束下的重力三维建模技术在研究在深、边部找矿和重力异常的精细处理等方面具有潜在的价值和广阔的应用前景. With the development of 3D geological information technology, 3D prediction is an important approach and development trend for large scale deep ore prospecting. In this paper,3D inversion of gravity anomaly is carried out,and Voxler software is used to perform the 3D visualization of the inversion results. The information in the study area such as drilling results,geological map,etc,are used as priori information after digitized and projected. An appropriate visual presentation was selected,and the final digital model was established which can reflect the structure of density distribution of the study area. Some geological interpretations and prospecting for unknown areas have been carried out based on this. The results show that the Voxler software can be used to reconstruct the 3D density distribution underground,the geological environment can be expressed and all of the data can be browsed,anlysised and researched intuitively by the 3D magnetic modeling. It shows that the gravity 3D modeling technology under the constraint of prior information has potential and broad applications in the study of deep and marginal ore prospecting and fine processing of gravity anomalies.
