Аннотация: The mineral and chemical composition of bauxites from the Chadobets uplift of the Siberian Platformis the total product of laterites on aluminosilicate rocks (source of aluminum) and on alkaline rocks andcarbonatites (source of rare earth elements (REEs), Nb, Ta, Th, U, etc.). The laterization of these rocks andsubsequent denudation led to the formation of unique bauxite deposits with a high content of rare and REEs.Supergene minerals of the laterite weathering crust are in a dispersed microcrystalline and amorphous state,which complicates their study and the choice of methods for extracting useful components. Precision methodswere used to establish the forms and compositions of the main supergene minerals, biomineral films, biomorphoses,and the distribution of rare and rare earth elements in them.
