Nickel-Cobalt Laterites?A Deposit Model

Nickel-cobalt (Ni-Co) laterite deposits are supergene enrichments of Ni Co that form from intense chemical and mechanical weathering of ultramafic parent rocks. These regolith deposits typically form within 26 degrees of the equator, although there are a few exceptions. They form in active continental margins and stable cratonic settings. It takes as little as one million years for a laterite profile to develop.
