Igneous Rocks Columbia University

Igneous Rocks Of the three principal rock types (igneous, sedimentary, and metamorphic), igneous rocks can be thought of as "primary" rocks because they crystallize from a liquid. Sedimentary and metamorphic rocks, which we will study later, may be thought of as derivative rocks.

Serpentinization is a processes whereby rock (usually ultramafic) is changed, with the addition of water into the crystal structure of the minerals found within the rock. A common example is the serpentinization of peridotite (or dunite) into serpentinite (the metamorphic equivalent). Here''s where it gets a bit fuzzy:
