【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。更多还原

【Abstract】 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.更多还原
