Popis:	Bauxite deposits are formed on karst topography because the sinkholesentrap aluminous materials subject to laterization. In the Jamaican deposits, these primary aluminous materials are mainly residuum from the White Limestone Formation, but may include some volcanic ash. In the Eufaula deposits, the source materials were kaolinitic claysderived from weathering of crystalline rocks of the Piedmont. The sinkholes provide downward drainage, and deposits formed in them are protected from erosion.
