Nickel laterite deposits are formed by the prolonged and pervasive weathering of Ni silicate-
bearing ultramafıc rocks, generally in tropical to subtropical climates. The deposits can be …

Ultramafic outcrops could represent up to 3% or more of the terrestrial surface and their
unusual geochemistry makes them a global hotspot for biodiversity. Ultramafic soils are a …

The book is structured thematically, encompassing principles, processes and products,
practice and applications. Discussion of processes that control heavy mineral assemblages …

In the Earth's crust, Ni is generally concentrated in mafic and ultramafic rocks and is coupled
with Mg in Mg-olivine, Mg-pyroxene and spinel. Whether the Ni-rich, and in general, the …

Part of the soils occurring in the serpentinite Szklary Massif (SW Poland) have developed in
Quaternary under temperate climate on the parent rock not affected by chemical weathering …

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 …

An upward loss of Ni is commonly reported in the oxide-rich unit of Ni-laterite deposits
developed over ultramafic rocks in tropical regions, especially in freely drained and deeply …

Abstract In Sabah, Malaysia, ultramafic rock outcrops are widespread (totalling 3500 km 2,
one of the main outcrops in the tropical zone), and predominantly of the peridotite type …

In the Lomié region (south-east Cameroon), strong weathering of serpentinized ultramafic
rocks has produced a thick laterite cover with significant nickel and cobalt contents. The …

Abstract In the Sri Lankan Highlands erosion and chemical weathering rates are among the
lowest for global mountain denudation. In this tropical humid setting, highly weathered deep …
