河北北岔沟门铅锌矿区地球化学特征

摘要

Based on an analysis of the distribution of elements in streamsediments, rocks, near-ore wallrocks and orebodies within the Beichagoumen lead-zinc ore district, this paper has probed into the correlations, compositional zoning and primary zoning of elements as well as their mineralization significance, described geochemical characteristics of the ore district, and established the basic criteria for evaluating the denudation extent. In addition, geochemical ore-prospecting indicators are put forward for future geological reconnaissance in this area.%通过对河北省隆化县北岔沟门铅锌矿区水系沉积物、岩石、近矿围岩、矿体中元素分布规律的分析，探讨了矿区内元素的相关性、元素组分分带及矿化意义和元素原生分带，阐明该矿区的地球化学特征，基本建立矿体剥蚀程度的评价指标，并对今后在该区进行地质普查提出了地球化学找矿标志。
