- •
High contents of Mn, Co, Ba, REE, Ta, W occur in georeferenced topsoils of Brava.
- •
REE and W can be used to trace outcrops of extrusive carbonatites.
- •
Iron is strongly oxidized in the majority of topsoils of Brava Island.
- •
Predominance of low oxidized magnetite in the topsoil of extrusive carbonatites
