Abstract The Santa Fé Ni laterite deposit (Brazil) developed as a consequence of weathering of serpentinized dunites that produced a regolith in which the main Ni ore zone is a ferruginous saprolite with chlorite as the main ore-carrier along with Ni-bearing Fe-oxyhydroxides. The genesis of chlorite...
