Definition

Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.

Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation

Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.

Sovites are formed due to low degrees of partial melting of rocks.
