The typical ore deposit of accumulate bauxite deposit is called Maijiuping accumulate bauxite deposit.  The metallogenetic material of it originates from the original sedimentary bauxite/rock bed.  The ore deposit is in the 4 main karst geomorphological types of karst funnel, karst slope, stone teeth slope and peak cluster valley of underlying Upper Palaeozoic Middle, Upper Devonian—Lower Permian horizon near the ore source bed.  The karst geomorphology controls the thickness and form of accumulate ore body.  The Al₂O₃, A/S and ore content of various accumulate types have a certain rule.
