Cette division s’opère suivant un ordre déterminé de précipitations d’après le degré de solubilité en fonction du changement des particularités physico-géographiques du dépôt. L'ordre est le suivant : Les oxydes d’aluminium sont les moins mobiles; après eux suivent les oxydes de fer et de manganèse, la silice colloïdale et d’autres composés.
