[HTML][HTML] Trace element geochemistry of iron-(oxy)-hydroxides in Ni (Co)-laterites: Review, new data and implications for ore forming processes
Abstract Iron-(oxy)-hydroxide (FeO/OH) phases are abundant in all supergene ore deposits.
The most common FeO/OH phase in supergene environments is goethite, although …

Parent rock and climatic evolution control on the genesis of Ni-bearing clays in Ni-Co laterites: New inferences from the Wingellina deposit (Western Australia)
Oxide-type Ni-laterites seldom contain significant Ni-phyllosilicates reserves. This study is
focused on the mineralogy of Ni-clays mainly occurring in the saprolite zone of the …
