This process often occurs during mountain-building and plate convergence, leading to foliated rocks with aligned mineral bands. Non-foliated metamorphic rocks including quartzite and marble form under lithostatic pressure. The text highlights serpentinite, California's state rock, known for its mineral serpentine.

It notes California's role as a passive margin during this time, with limited tectonic activity leading to sedimentary rock accumulation. The rifting of Rodinia formed sedimentary basins and marine incursions, resulting in thick Precambrian marine sediments, which are now only partially visible in California, especially in the southeast.

It distinguishes between foliated and non-foliated types and explores contact and regional metamorphism. Common examples like slate, schist, quartzite, and marble are highlighted, along with their applications in construction and art. Key concepts related to metamorphic rocks and their uses are emphasized throughout the lesson.
