河南东闯金矿床507号脉金及相关元素原生晕异常特征及深部成矿远景评价

The anomalous feature of primary halo of gold vein No.507 and its related elements in Dong Chuang gold deposit of Henan Province and the evaluation of deep mineralization prospect

矿床原生晕地球化学异常特征研究是矿区大比例尺成矿预测的重要途径。本文研究了东闯金矿床５０７脉Ａｕ及相关元素地球化学异常特征，建立了元素轴向分带序列，并根据研究结果推断５０７脉１８７１ｍ中段以下部位有较好成矿远景。

The study on geochemical anomalous feature of primary halo of ore deposit is an important approach to mineralization prediction in large scale.This paper studied the geochemical abnormal feature of gold and gold related elements of vein No.507 and established the axial zoning sequence of elements. According to the results of those study ,It was predicted that a good mineralization perspective existed under 1871m level in vein NO.507.This conclusion provides important evidence for deep prospecting in the mining district.
