  • Peridotite: Mineral information, data and localities.

    A peridotite is an ultramafic rock containing more than 40% olivine ( Mg2SiO4 ). A general term for a coarse-grained plutonic rock composed chiefly of olivine with or without other mafic minerals such as pyroxenes, amphiboles, or micas, and containing little or no feldspar. Accessory minerals of the spinel group are commonly present.Foliar metal accumulation in plants from copper-rich,2015-1-30 · Such deposits are known to occur in peridotite-associated ultramafic rock as part of the ophiolite suites in Sabah, Malaysia (Newton-Smith 1967). Abnormally high Cu concentrations (likely of the same geologic origin) have also been observed in Brazil (Brooks et al. 1990,1992 ) and Sri Lanka (Rajakaruna and Bohm 2002 ; Rajakaruna and Baker 2004 ).
