Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

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

Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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