黔东北地区优质锰矿产于早震旦世大塘坡早期黑色岩系底部 ,位于普通锰矿———菱锰矿层的下部。作者在论述区内锰矿成矿的岩相古地理、古构造、成锰盆地特征的基础上 ,对优质锰矿的分布产出规律进行了分析和论述 ,并对区内优质锰的潜力进行了评估 ,可望成为我国重要的优质锰矿勘查开发基地。
The high-quality manganese ore in the northeast of Guizhou Province is found in the bottom of the early black rock series of the Datangpo of Early Sinian and is located in the lower part of the common manganese ore --- rhodochrosite. Based on the discussion of lithofacies palaeogeography, palaeotectonics and Mn-forming basins in the ore-forming area of manganese ore in the area, the author analyzes and discusses the law of the distribution and output of high-quality manganese ore and evaluates the potential of high-quality manganese in the area , Is expected to become China’s important high-quality manganese exploration and development base.
