Dissolved manganese was concentrated in relatively anoxic waters of the intracratonic basin during a marine transgression and precipitated as oxides and carbonates during a regression. Ore bodies ultimately formed by concentration of abundant particulate manganese by a tidal-lag mechanism. This content is PDF only. Please click on the PDF icon to access.
