| 摘 要： | 本文报导了贵州省松桃县新发现的一个全隐伏的超大型锰矿床——道坨锰矿床的地质地球化学基本特征,为进一步开展科学研究奠定基础。矿床赋存在新元古代成冰系（南华系）大塘坡组底部的含锰碳质页岩中,主要由条带状、块状、气泡状菱锰矿矿石组成。主量元素特征为Al2O3、TiO2、Fe2O3含量较低,中等程度的P2O5富集,MnO、MgO含量相对较高,Fe/Mn比值低。微量元素特征为Rb、Nb和Pb亏损,Co、Zn、Sr、Mo相对富集。稀土元素总稀土含量高、中稀土轻微富集、Ce的正异常明显为特征。道坨锰矿含锰层位中黄铁矿的δ34S-VCDT值异常高,并且变化范围小,所测试黄铁矿的δ34S-VCDT值介于56.2‰63.3‰,平均60.8‰。新发现的道坨超大型锰矿床属于典型的大塘坡式锰矿床,其发现不仅为研究新元古代大规模成锰作用提供了新机遇,同时也为研究成冰系环境演化及其资源、生物效应提供了新契机。
