Overview. Nonfoliated metamorphic rocks lack foliated texture because they often lack platy minerals such as micas. They commonly result from contact or regional metamorphism. Examples include marble quartzite greenstone hornfel and anthracite.- stone/ Serpentinite ( Foliated Metamorphic Rock) I chose the serpentinite rock due to its incredible look and its color. Serpentinite can be found in the Coast Ranges, the Klamath Mountains, and in the Sierra Nevada foothills. T h e serpentinite is formed by the hydrous alteration and low-temperature metamorphic alteration of igneous ultramafic rocks.

The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8). As already noted, slate is formed from the low-grade metamorphism of shale, and has microscopic clay and mica crystals that have grown perpendicular to the stress.

There was once a breccia that formed in a fault zone and was later metamorphosed under confining pressure, resulting in this nonfoliated metabreccia. It indicates faulting (brittle behavior at shallow depths in the crust) followed by either burial metamorphism in a sedimentary basin or contact metamorphism by an intruding magma body.
