碧流台铅锌矿床是大兴安岭南段新发现的铅锌矿床,位于黄岗一甘珠尔庙一乌兰浩特成矿带东部,赋存于二叠系林西组浅变质岩系中,主要受到北东向构造控制。通过对矿区1:1万土壤地球化学数据进行参数统计,以及单元素异常分析、聚类分析、因子分析、因子异常分析处理,确定F1因子(Ag-Pb-Zn-Mn组合)异常区为重要的银铅锌找矿标志。通过对高精度磁法测量数据进行化极、延拓、水平一阶导数、垂向二阶导数处理,提取结构面/线性构造、地质体/环形构造。在地质勘查工作的基础上,结合土壤地球化学异常和高精度磁法测量解译结果,提取地质、地球化学、地球物理找矿标志,为进一步找矿方向的确定及工程布置提供依据。
The Biliutai Lead-Zinc Deposit, a newly discovered deposit in the southern section of the Greater Khingan Mountains, is located in the eastern part of the Huanggang-Ganjur Temple-Ulanhot metallogenic belt. It is hosted in the shallow metamorphic rock series of the Permian Linxi Formation and primarily controlled by NE-trending structures. By analyzing 1:10 000 soil geochemical survey data through parameter statistics, single-element anomaly analysis, cluster analysis, factor analysis, and factor anomaly analysis, the F1 factor anomaly zone (Ag-Pb-Zn-Mn assembly) was identified as a critical prospecting indicator for silver-lead-zinc mineralization. High-precision magnetic survey data were processed using reduction-to-pole, continuation, horizontal first derivative, and vertical second derivative methods to extract structural planes/inear structures and geological bodies/ring-shaped structures. Building on geological exploration, combined with soil geochemical anomalies and high-precision magnetic survey interpretations, this study integrates geological. geochemical, and geophysical prospecting indicators to provide a basis for determining further prospecting directions and engineering layouts.
