Peridotites and other ultramafic rocks
Geology TodayPeridotites are a group within the category of ultramafic rocks. These are usually dark‐coloured rocks rich in magnesium, poor in silica and lacking feldspars. Earth's mantle, which makes up 83 percent by volume and 67 percent by weight of the planet, consists largely of peridotite, which, although relatively sparse at the surface, therefore, is Earth ...

Tectonophysics, 1969
Abstract A subdivision of the orogenic peridotites into ophiolitic (or truly Alpine-type) and “root-zone” peridotites is proposed, and their differences in tectonic setting and metamorphic facies are discussed. Some current hypotheses for the origin and mode of emplacement of the orogenic peridotites are briefly reviewed.
