采用新创立的相关地球化学元素浓度级次（n值）特征对比模型和相近率线性判别模型对川北甘南地区产于三叠纪地层中的金矿成矿预测进行了研究。该方法在筛选找矿靶区、开展矿床地球化学模型研究等方面均取得了较佳应用效果。
The gold mineralization prediction of gold deposits in Triassic strata in Gannan area of northern Sichuan was studied by using the newly established geochemical element concentration grade (n-value) feature comparison model and the close-rate linear discriminant model. The method has achieved good results in screening ore prospecting targets and carrying out research on the geochemical model of ore deposits.
