Mn-ore deposits in Iron Ore Group, India, were previously classified in to: Stratiform, Stratabound and Lateritoid category

This paper reports another category from the above geological set-up and termed it as “Reworked Manganese Deposit” (RMD)

RMD is further grouped as: Detrital, Mangcrete and Wad deposits. The Detrital type is similar as that of Lateritoid deposit

Field distribution and petrography of RMDs reveal their formation at a later stage under different environmental conditions
