河南洛宁地区物化探异常特征及找矿效果

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。

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

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.
