Application of the weights-of-evidence method in mineral resource assessments in the southern segment of the “Sanjiang metallogenic zone”, southwestern China

  • 摘要: 提要:证据权法本身是一种离散的多元统计方法。阐述了矿物资源潜力区的概念,简述证据权法的基本原理。以西南“三江”南段为例,首先在地质、地球物理、地球化学以及遥感地质等致矿信息提取的基础上,运用证据权法定量分析各类致矿信息(控矿因素)与矿产资源空间分布的关系;进而选择最佳控矿因素作为资源评价变量,据其变量计算每个单元的后验成矿概率;最终根据后验成矿概率定量圈定和评价找矿靶区。实践证明:在GIS环境下,“证据权”与找矿信息结合能够有效区分矿化有利地段和不利地段,从而达到定量快速圈定和评价找矿靶区之目的。整个过程是借助于MOPAS3.0评价系统实现的。
    Abstract: Abstract:The weights-of-evidence method is a discrete multivariate statistical method. It elucidates the concept of mineral resource potential areas and briefly describes the basic principle of the weights-of-evidence method. Take for example the southern segment in the "Sanjiang" metallogenic zone of southwestern China, the spatial relationship between various kinds of ore-forming information (ore-controlling factors) and mineral resource distribution is quantitatively analyzed by using the weights-of-evidence method on the basis of extraction of ore-forming information from geological, geophysical, geochemical and remote sensing geological data. Then the best ore-controlling factors are chosen as the variables for mineral resource assessments, which are used for calculating the posterior ore-forming probability of each unit. Eventually, ore-finding target areas are quantitatively delineated and evaluated according to their posterior ore-forming probabilities. This case study has illustrated that under the GIS environment the favorable mineralized areas can be effectively distinguished from the unfavorable ones through the combination of the "weights-of-evidence method" with ore-finding information so that the goal of fast quantitative delineation and assessments of the ore-finding target areas may achieved with the help of MORPAS3.0.
