湖南省邵阳盆地锰矿层特征及矿床富集规律探讨

摘要

Shaoyang Basin is a hollow zone formed in late Devonian epoch,and Permian Gufeng Formation is the main manganese-bearing horizon of this area.Ore bed 1-2 of Gufeng Formation has low grade of man-ganese.However,the ore beds are characterized by large ore bed thickness,wide distribution and great re-source potential.Therefore,analysis and summarization of the characteristics of manganese-bearing ore beds and the enrichment regularity of deposits has great implications for next round prospecting works of manga-nese in Shaoyang Basin.%邵阳盆地为泥盆世晚期形成的一凹陷带，二叠系孤峰组为该区主要含锰层位。孤峰组含锰1~2层品位较低，但矿层厚度大，分布面积广，资源潜力大，因此分析总结锰矿层特征、矿床富集规律，对指导邵阳盆地开展新一轮锰矿找矿工作具有重要意义。
