| 摘 要： | 通过对云南个旧芦塘坝研究区成矿信息分析,结合三维可视化技术,对其进行深部隐伏矿体预测。根据研究区的地质概况与成矿规律,确定地层和断裂是主要的控矿条件,利用三维建模软件建立该研究区的数字矿床模型,应用立方体预测模型找矿方法,提取成矿有利因子——地层、断裂、构造定量化信息、化学元素异常,将其作为预测变量,最终通过计算圈定出预测远景区进而优选出4个预测靶区。预测远景区结果表明,该研究区有较好的找矿潜力,其矿产预测方法有效性较好。构造定量化信息分析方法的应用有助于实现三维找矿。

| Abstract: | By analyzing ore-forming information of Lutangba study area in Gejiu,Yunnan Province,authors made a prediction of blind ore body with the help of 3D visualization technology.We took the stratigraphy and fracture as mainly ore-controlling factors according to geological feature and mineralization law,constructed digi-tal deposit model by means of 3D modeling software.Advantageous factors of ore-formation are extracted,including stratigraphy,fracture,quantitative information of structures and chemical elements abnormal as predictive variable by using method of the cubic predicting model.And finally we utilized delineate prospect area and then outline 4 targets.The prospective areas show that the study area has a good potential for prospecting minerals and the method of ore prediction is very effective.The application of the analysis method which is quantitative information of structures as new prospecting variables achieve a new breakthrough in 3D prospecting minerals. |
