| 摘 要： | 西藏谢通门县雄村铜金矿是在冈底斯成矿带中发现较早,勘探工作也开展较早的大型铜金矿床,是冈底斯成矿带上具有代表性的岛弧型斑岩铜金矿床,对该矿床的深入研究,为在相似地质条件下寻找"雄村式"矿床具有重要的指导意义。本文在总结雄村铜金矿床成矿地质条件和控矿因素的基础上,以该矿床的地质描述模型为依据,以矿区勘探资料为数据基础,将三维地质建模和可视化这一高新技术应用于该矿床,建立了雄村铜金矿的数字矿床模型,充分展示了立体模型对地质体空间特征的有效表达,实现了该矿床的数字化、可视化和动态化管理。同时,将数字矿床模型与矿区的大比例尺高精度磁测数据结合,开展多源信息三维综合分析,为矿区深部和外围三维定位定量预测提供有力的技术支持。

| Abstract: | The Xiongcun porphyry copper-gold deposit was found and explored earlier in the Gandise metallogenic belt,accumulating a wealth of data.It is a kind of typical island arc type porphyry copper-gold deposit in this belt.A thorough study of this deposit is of great significance for tracing the "Xiongcun type" deposits in similar geological settings.This paper summarized the ore-forming geological conditions and the ore-controlling factors of Xiongcun porphyry copper-gold deposit and used 3D geological modeling and visualization technology to build its digital deposit model based on the geological exploration data to show the deposit in three-dimensional space and to manage the deposit visually and dynamically.At the same time,the combination of the digital deposit model withthe large-scale aeromagnetic data could provide strong technical support for the deep and peripheral quantitative prediction of the mining area in three-dimensional space. |
