Many amphibolites are non-foliated and have this homogeneous and massive appearance. Figure 10.39, however, is a hand specimen of a garnet amphibolite, reminding us that amphibolites need not be nondescript and that they may be foliated.

Metamorphic rocks, meta- meaning change and – morphos meaning form, is one of the three rock categories in the rock cycle (see Chapter 1 ). Metamorphic rock material has been changed by temperature, pressure, and/or fluids. The rock cycle shows that both igneous and sedimentary rocks can become metamorphic rocks.
