Geologica Acta, 2006 Ultramafic rocks, mainly serpentinized peridotites of mantle origin, are mostly associated with the ophiolites of Mesozoic age that occur in belts along three of the margins of the Caribbean plate. The most extensive exposures are in Cuba. The ultramafic-

Peridotite weathering is the missing ingredient of Earth’s continental crust composition
Nature Communications, 2018 The concentration of Ni and Cr of the continental crust cannot be explained by formation models involving differentiated magmatic rocks. Here, the authors show that hydrothermal alteration and chemical weathering of ultramafic rock compensates for the ...

Mineralised ultramafic rocks in South Greenland
Rapport Grønlands Geologiske Undersøgelse, 1971 In 1960 several mineralised ultramafic boulders with a remarkable content of Pt were found by M. Loretan in the neighbourhood of Sarqa fjord in the Nanortalik district, South Greenland. This stimulated interest in a closer examination of the mafic and ultramafic rocks of South Greenland and in 1962 and 1963 J. P.
