The OCBIL theory comprises a set of hypotheses to comprehend the biota of old, climatically
buffered, infertile landscapes (OCBILs). Here, we review evidence from the literature to …

Nickel laterite ores account for over 60% of global nickel supply. They are the product of
intensive deep weathering of serpentinites under humid tropical conditions. Nickel is …

The geological evolution of New Caledonia may be divided into three phases. The
Gondwanan phase (Permian–Early Cretaceous), is marked by subduction along the SE …

Supergene processes related to downward water migration and dissolution of primary
minerals in the New Caledonian peridotites result in Ni enrichment at the bottom of the …

Abstract The European Union recently updated the list of raw materials considered as critical

The growing demand for scandium (Sc), essential for several modern industrial applications,
drives the mining industry to develop alternative Sc sources. In such context, significant Sc …

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 …

Convergence and subduction started in the Late Paleocene, to the east of New Caledonia in
the South Loyalty Basin/Loyalty Basin, leading to the formation of the Subduction–Obduction …

The main metallic mineral resources of New Caledonia are hosted by the obducted
