Peridotites

The original home of platinum is in basic igneous rocks, such as peridotites, pyroxenites, and dunites, where it has been found in small, scattered crystals intergrown with olivine, pyroxene, and chromite. ❋ Unknown (1915)

In some cases, also, talc results from the alteration of igneous rocks without mashing -- as in the case of the large talc and soapstone deposits of Virginia, which are the result of rather complete alteration of basic igneous rocks such as peridotites and pyroxenites. ❋ Unknown (1915)

MORBs and thermobarometrically determined fO2s of abyssal peridotites and MORB glasses, the fO2 ❋ Unknown (2006)

Like enstatite, bronzite is a constituent of many basic igneous rocks, such as norites, gabbros, and especially peridotites, and of the serpentines which have been derived from them. ❋ Various (N/A)

They are thought predominantly to be peridotites, which comprise magnesium-rich, silicon-poor minerals such as olivine and pyroxene. ❋ Unknown (2011)

The conductors found by the old airborne survey appear to rim a circular magnetic high that is likely due to a mafic intrusion that is also a characteristic of peridotites. ❋ Unknown (2010)

The BIF units are intruded by gently dipping porphyritic dykes, and appear to be surrounded by mostly peridotites and other ultramafic units. ❋ Unknown (2009)

The chromite-bearing horizon, which is hosted by a thick package of olivine-bearing peridotites and pyroxenites, lies directly between the Black Thor chromite discovery of Freewest Resources ( 'Freewest') and the Freewest/KWG Resources/Spider Resources Big Daddy chromite zone and northeast of Noront Resources Blackbird discoveries. ❋ Unknown (2009)

Hydrated oceanic peridotites form large bodies and also melanges along the northern coast of Dominican Republic. ❋ Unknown (2009)

Saumur et al. examined serpentinites in northern Dominican Republic and found two different origins: hydrated oceanic peridotites and subarc mantle peridotites. ❋ Unknown (2009)

Mineralized peridotites were noted in the area (peridotites are known to host Platinum ❋ Unknown (2010)
