Quartzite is a metamorphic rock formed under immense heat and pressure in the earth. It can be polished to a glassy shine, and its beautiful colors and patterns make it popular for use as kitchen countertops, stairs, and flooring. Commercial uses include making roofing tiles and using the crushed stone in road construction.

All metamorphic rocks are derived by the action of heat and/or pressure on pre-existing igneous, sedimentary, or metamorphic rocks. The pre-existing rock is called either the parent rock or the protolith. Your textbook incorrectly uses the term “source rocks” for the pre-existing rock. The term source rock used in sedimentary deposits to

The four most common types of foliated rock, in order of increasing metamorphic grade are slate, phyllite, schist, and gneiss. These four different kinds of rocks all contain different metamorphic minerals and fabrics and vary depending on their protolith compositions. We discuss each in more detail below.

: 168Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance. Minor amounts of former cementing materials, iron oxide, silica, carbonate and clay, often migrate during recrystallization, causing streaks and lenses to form within the quartzite. [1]

The Geological Strength Index (GSI) system is widely used for estimating the strength reduction from an intact rock to a rock mass, introduced by Hoek [12] in 1994. It is a unique rock mass classification system used as part of the Hoek–Brown failure crite‐rion for estimating the strength and stiffness of a rock mass [21,22].
