3D ModelNoAI

Locality: Africa (unknown country)

Size: 5 cm x 3 cm x 2 cm

Type: Igneous ultramafic rock (peridotite) + extrusive igneous rock (basalt)

Description: Xenolith is a fragment of a foreign rock (peridotite) enclosed in an igneous rock (in this case basalt). (Gk. xenos, guest, foreign + lithos, stone) Peridotite is the principal rock type in the mantle. Peridotites are predominantly composed by Olivine (40-60%), pyroxenes, amphiboles, ferromagnesian mica, and melilite.

Essential minerals: olivine, clinopyroxene, orthopyroxene

Non-essential minerals: chromite, spinel, etc.
