Foliation is a term used that describes minerals lined up in planes. Foliated rocks typically appear as if the minerals are stacked like pages of a book, thus the use of the term ‘folia’, like a leaf. Nonfoliated rocks have minerals that do not show a preferred orientation.

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.

Certain minerals, most notably the mica group, are mostly thin and planar by default. Foliated rocks typically appear as if the minerals are stacked like pages of a book, thus the use of the term ‘folia’, like a leaf. Other minerals, with hornblende being a good example, are longer in one direction, linear like a pencil or a needle, rather than a planar-shaped book.

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.
