河南洛宁地区物化探异常特征及找矿效果

ANOMALY OF GEOPHYSICO-GEOCHEMICAL EXPLORATION AND ITS PROSPECTING EFFECTIVENESS IN THE LUONING AREA, HENAN

该区经１：５万分散流扫面，发现Ａｕ，Ａｇ，Ｃｕ，Ｐｂ，Ｚｎ异常数十处。其中Ａｕ，Ａｇ，Ｐｂ等元素异常成带状展布。在对找矿有望异常进行了１：１万次生晕、原生晕，激电中梯等多方法的综合研究后，验证结果表明，物化探方法在本区寻找金、银矿床和预测隐伏含矿构造带效果显著。

Tens of geochemical exploration anomalies of Au, Ag, Cu, Pb and Zn have been discovered by the use of the 1:50000 dispersion train survey, in which Au, Ag and Pb anomalies extend zonally. The verification of the 1: 10000 secondary halo, primary halo and intermediate gradient of induced polarization in the hopeful anomalous area indicates that geophysico-geochemical prospecting is a remarkably effective method in the prospecting of gold and silver deposits and in the predicting of hiddenore-bearing structural belts in the Luoning area.
