peridotite's Usage Examples:

Some of the suggested instability mechanisms include dehydration embrittlement caused by the breakdown of antigorite or chlorite in a hydrated peridotite upper mantle, and un-bending of the slab.

The peridotite below the ocean crust, "abyssal peridotite," is found on the walls of rifts in the deep sea floor.

Pre-deformation they would have been a combination of undepleted mantle in the form of lherzolite, peridotite and depleted harzburgite.

Among the rocks that commonly include peridotite xenoliths are basalt and kimberlite.

sources peridotite (variety harzburgite) so enriched, especially in potassium pyroxene and phlogopite-rich volumes within the mantle, not from peridotite alone.

Xenoliths of dunite, peridotite and spinel lherzolite in basaltic lava flows are one example.

In an occurrence at Mount Clifford, Australia, it occurs associated with a nickel sulfide orebody adjacent to a gabbro which intruded peridotite.

diamonds from eclogite xenoliths have a 13C:12C isotope ratio different from that typical of diamonds from peridotite xenoliths.

equivalents of ultramafic cumulate rocks such as peridotite and dunite.

Mantle-peridotite xenolith from San Carlos Indian Reservation, Gila Co.

It is also found in alpine peridotite massifs that represent slivers of sub-continental mantle exposed during collisional.
