Abstract
Weathering processes and infiltration metasomatic processes in the weathering crusts hyperbasite arrays have a positive effect on the accumulation of rare earth elements. The content of rare earth elements is steadily increasing bottom-up on the profile of weathering. Metasomatic upper profile characterized by a high content of rare earth elements, which leads to the appearance of rare earth elements phosphate mineral phase – xenotime found in this laterite for the first time. The composition of the rare earth elements in incorporating their metasomatic and minerals demonstrates chondritic distribution.
