Pyrochlore nanomineralogy questions the immobility of niobium during tropical weathering

Quentin Bollaert, Mathieu Chassé, Nicolas Menguy, Corentin Le Guillou, Artur Bastos Neto, David Troadec, Laurence Galoisy, Georges Calas

The origin of the mobility of low-solubility elements such as niobium during supergene weathering remains elusive, despite growing evidence, especially in strongly weathered regolith. In the critical zone, the low mobility of these high field strength elements (HFSEs) is assigned to the resistance...
