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.
