云浮硫铁矿矿床地质特征及找矿实践

Ore Deposit Geological Characteristics and Ore-prospecting Practice of Yunfu Pyrite Mine

云浮硫铁矿赋存于震旦纪浅变质岩中,矿床成因复杂,总体呈现同生沉积-热液交代-热液充填等多期成矿的特征。在对矿床地质特征分析的基础上,首先分析了矿床成因,然后对近年来在矿区深部及周边空白区域开展的以铅、锌、金等为目标矿种的找矿成果进行讨论,最后对目前找矿工作进行总结,为在该地区进一步开展找矿工作提供参考。

The Yufu pyrite ore deposit occurences in the Sinian period shallow metamorphic rock,genesis of ore deposit is complex,with the characterisitcs of mutiperiodic mineralization of syngenetic sedimentary-hydrotheral metasomatic-hydrothermal filling on the whole. The ore deposit geological characteristics is analyzed,based on this,firstly,the genesis of ore deposit is discussed; secondly,the ore-prospecting results of the prospecting work of lead,zine,gold which conducted in the deep area and surrounding area of the Yufu pyrite mining area in recent years is analyzed; finally,the current ore-prospecting work is summarized so as to provide some reference for the further ore-prospecting work in the mining area.
