摘　　要：通过对河南汝阳王坪西沟大型铅锌矿床地球化学特征的分析研究,揭示了利用土壤化探作为有效手段,发现并查明铅锌矿床的基本思路。同时证实,土壤化探在铅锌找矿方面效果是好的。通常,主要工业铅锌矿体均限制在Pb、Zn、Ag、Cu组合异常的外边缘以内,而且其成矿母岩等主成矿元素Pb、Zn只要大于涂和费及维诺格拉多夫值有关中性岩Pb含量2.5倍、Zn丰度值2倍以上,均可列入与找矿有利的原生晕异常。An analysis of geochemical characteristics of the Wangpingxigou large-size lead-zinc deposit in Ruyang of Henan Province reveals that soil geochemical exploration is an effective means in search for lead-zinc deposits. The main economic lead-zinc ore bodies are on the whole confined within the outer margin of the Pb, Zn, Ag and Cu composite anomaly. Where the Pb values and Zn values of the ore-forming parent rocks are 2.5 times and 2 times higher than their respective Tu Hefei＇s and Venogradov＇s values of intermediate rocks, they can be regarded as the primary anomalies favorable for ore prospecting.
