Serpentinite foliated or nonfoliated.

Foliated metamorphic rocks such as gneiss, phyllite, schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite and novaculite do not have a layered or banded appearance.SERPENTINITE - NONFOLIATED - Grade: VARIABLE .

Quartzite - foliated or non-foliated granoblastic metamorphic rock composed of > 90% quartz. Foliation if present can be defined by either elongation of quartz grains and/or aligned, sparse micas. 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.
