摘要
湖南省已有普查资料的氧化锰矿床(点)50余处,遍及全省30余个县市。地理分布上显示出北少南多的特征。层位上板溪群、震旦系、奥陶系、泥盆系、二叠系、第四系均有分布,绝大部分储量分布在晚古生代以后的地层中,以泥盆系、第四系及二叠系为主。矿床类型主要有淋滤型、锰帽型和堆积型三种。矿石质量特点:贫矿多,富矿少,锰低铁高、磷硫中偏低、伴生金属丰富。
There are over 50 manganese oxide deposits with reconnaissance data in Hu- nan province,widely distsibuting over more than 30 cities and counties。In view of geographical distribution,there are less deposits in the north and more in the south,In view of layer,the re- sources are from panchi group,the sinian system,the ordovician system,the Devonian system,the Permian system,the Quarternary system。Most of resources are distributed in the layers after later palaeozoic Era,taking the Devonian system,the Quarternary system and the permian system as the dominant systems。Types of deposits are leached,manganese capped,and stocked types。The qualitical characteristics of the ores are:poor ore more,rich ore less,manganese content low,iron content high,phosphorus and sulphar medium,associated metals abundant.
