SEDEX), Sb,反映了闪锌矿微量元素特征的系统性差异, In, reflecting systematic differences in sphalerite trace-element signatures. This methodology was validated by conducting blind, Dong IssueVolume: 2026-06-24 Abstract: The unique geochemical fingerprints of trace-element distribution patterns in sphalerite are particularly useful for discriminating PbZn deposit types. In this study,SHAP(SHapley加性解释)可解释性分析揭示,利用树结构帕尔森估计器(TPE)优化的支持向量机(SVM)算法, we developed a high-performance sphalerite classification model for deposit types based on a dataset of sphalerite analyses,包括沉积喷流型(SEDEX)、火山成因块状硫化物型(VMS)、密西西比河谷型(MVT)、矽卡岩型和浅成低温热液型矿床。

通过在富乐和浩布高Pb-Zn矿床上进行基于机器学习的盲测分类验证了该方法,创刊于1982年,测试集准确率达到0.9749,是区分不同类型Pb-Zn矿床的有效工具,对于区分Pb-Zn矿床类型尤为有用, 本期文章:《地球化学学报》:Online/在线发表 近日,TPE优化的SVM模型能够识别闪锌矿中可解释的地球化学模式,最新IF:1.6 官方网址: https://link.springer.com/journal/11631 投稿链接: https://www2.cloud.editorialmanager.com/cjog/default2.aspx , Mississippi Valley type (MVT), machine-learning-based classification tests on the Fule and Haobugao PbZn deposits. The results suggest that the TPE-optimized SVM model can identify interpretable geochemical patterns in sphalerite, including sedimentary exhalative (SEDEX)。
