The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes.

Marble metamorphic rock grade.

Increasing metamorphic grade decreasing metamorphic grade increasing degree of contact metamorphism. Slates are predominantly realigned clay minerals. As you can see in the photo above schist is a more coarse grained rock.

The individual grains of minerals can be seen by the naked eye. Marble is a metamorphic rock that forms from a _____ parent. Schist is a medium grade metamorphic rock.

The specimen shown above is a chlorite schist because it contains a significant amount of chlorite. As metamorphic grade continue to increase, sheet silicates become unstable and dark minerals such as hornblende or pyroxene start to grow. Marble begins as the sedimentary rock known as limestone, and then, because of intense heat and pressure, it changes into marble, known for its.

It contains sharp, broken clasts while conglomerate has smooth, round clasts. Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture.metamorphism takes place at temperatures in excess of 150 to 200 °c (300 to 400 °f), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. Breccia is a rock made of smaller rocks, like a conglomerate.

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). All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure.

Schist is a foliated metamorphic rock that is well developed and contains substantial amounts of mica. It is a rock of intermediate metamorphic grade between phyllite and gneiss. For example, if the protolith is known to be basalt, the rock will be described as a metabasalt.
