摘要
靶区优选是矿产勘查中的一个关键环节,它既是矿产资源预测成果的直接体现形式,同时又是联系矿产资源预测与勘查工作部署的桥梁.然而,由于人们认识上的不完备性和缺乏相应的技术手段支撑,使得靶区优选常被忽视或简化.探讨了靶区优选的地质基础原则,建立了靶区优选的技术流程,研发了基于GIS支持下靶区优选计算机辅助决策模块,并以云南省个旧地区与岩浆活动有关的锡铜多金属矿靶区为例进行了示范研究.结果表明靶区优选技术及相应的软件能够客观地反映不同靶区的特征,提高靶区优选的智能化程度和工作效率.
Optimum target area (OTA) plays an important rule in mineral resource prospecting, which is not only the end production of mineral resource assessment, but also the bridge between the mineral resource assessment and exploration plan. However, it is usually ignored or simplified owing to the incomplete cognition and being lack of technique or software. In this paper, we disscuss the OTA principles based on the geology, set up the data flow for OTA and develop the GIS-based OTA model. The Gejiu, Yunnan, southwestern China, was chosen as an example to do the demonstration research, The results demonstrate that the OTA model could reflect the properties of target areas, and can enhance the efficiency of OTA.
