贵州二叠系与南华系锰矿地质特征及控矿条件

2-Stack System in Guizhou and South China Manganese Ore Geological Features and Control Conditions in South China

依据地层学的对比研究,遵义、贵州水城—纳雍的锰矿均产于中二叠统茅口组第二段,遵义锰矿主要为碳酸锰矿床,水城—纳雍锰矿主要是锰帽型次生氧化锰矿床。黔东北锰矿均产于南华系大塘坡组一段,主要为碳酸锰矿床。黔东北大塘坡式锰矿床属于典型的古天然气渗漏沉积型锰矿床。通过典型的古天然气渗漏沉积型锰矿床模型以及贵州水城—纳雍一带的锰矿控矿条件,为研究黔东北锰矿古天然气渗漏沉积型锰矿床、水城—纳雍一带锰矿床预测深部找矿具有重要意义。旨在通过贵州中二叠系茅口组第二段的遵义、贵州水城—纳雍锰矿、黔东北南华系大塘坡组一段锰矿地质特征的概分析,探讨区内锰矿控矿地质条件,以期扩大找矿远景。

According to the comparative study of stratigraphy,manganese ore in Zunyi of Guizhou Water City are produced in the second section of the second stack of the Two-fold Maokou Group.Zunyi is of ore mainly for the carbonic manganese deposit.Nagao manganese ore is mainly manganese cap type secondary manganese oxide deposit.The North-east manganese ore is produced in South China Department of Big Tong Slope Group section,mainly for the carbonated manganese deposit.The North-east Datang slope-type manganese deposit belongs to the typical ancient natural gas leakage deposition-type manganese deposit.Through the typical model of ancient natural gas leakage deposition-based manganese deposit and the conditions of manganese ore control in the area of Guizhou Water City-Nagao,it is of great significance to study the deep prospecting of deep prospecting for the study of the ancient natural gas leakage sedimentary manganese deposit shimiletins and the Water City-Nagao area.The aim is to explore the geological conditions of manganese ore control in the region through the general analysis of the geological characteristics of the Zunyi,Guizhou Water City-Nagao manganese mine,including the Datang Slope Group of the South China department in Northeast China in the aim of expanding the prospect of prospecting.
