黔北晚二叠世初形成的锰矿床。过去认为是浅海相、海陆交互相沉积矿床;关于锰质来源也有火山、大陆、碳酸盐基底之说。通过研究,作者认为黔北锰矿床为一岩溶沉(堆)积矿床。东吴运动使黔北抬升,在岩溶化过程中,“白泥圹层”被风化剥蚀,沉(堆)积在盆地中,经还原富集成矿。 The Manganese Deposits Developed in Late. In the past, it was considered as a shallow marine facies, sea-land interactive sedimentary deposit; there are also volcanic, continental and carbonate basalts on the source of manganese. Through the study, the authors believe that Qianbei Manganese ore deposit is a karst (pluton) deposit. During the karstification process, “Bai Nai” layer was weathered and eroded, and Shen (heap) accumulated in the basin and was enriched and mineralized by reduction.
