Olivine, of which peridot is a type, is a common mineral in mafic and ultramafic rocks, often found in lava and in peridotite xenoliths of the mantle, which lava carries to the surface; however, gem-quality peridot occurs in only a fraction of these settings. Peridots can also be found in meteorites.
Dunite is found as prominent veins in the peridotite layer of ophiolites, which are interpreted as slices of oceanic lithosphere (crust and upper mantle) thrust onto continents. [6] Dunite also occurs as a cumulate in layered intrusions , where olivine crystallized out of a slowly cooling body of magma and accumulated on the floor of the magma ...
Dunite is rarely found within continental rocks, but where it is found, it typically occurs at the base of ophiolite sequences where slabs of mantle rock from a subduction zone have been thrust onto continental crust by obduction during continental or island arc collisions . It is also found in alpine peridotite massifs that represent slivers ...

A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material. [citation needed] This is a list of those minerals, excluding minerals also commonly found in terrestrial rocks. As of 1997 there were approximately 295 mineral species which have been identified in meteorites.
Locally, beads of turquoise and lazurite are found. Göbekli Tepe, Anatolia, dating back to the 10th–8th millennium BC. Note: nephrite is a microcristalline variety of tremolite (ferro-actinolite–tremolite solid solution series); white nephrite is almost pure tremolite and iron gives nephrite its green colour.
The Roman navigators brought gold coins, peridots, thin clothing, figured linens, multicoloured textiles, sulfide of antimony, copper, tin, lead, coral, raw glass, wine, realgar and orpiment. [ 12 ] [ 13 ] The locations of unearthed coin-hoards from Pattanam suggest an inland trade link from Muziris via the Palghat Gap and along the Kaveri ...
