Classification of Metamorphic Rocks
Affected by wide ranges of temperature and pressure, metamorphic rocks are often the most difficult of rocks to identify. The naming process can be simplified by keeping two things in mind, texture and mineralogy.

Metamorphic Rocks
Not all rocks occur from volcanoes, or from the deposition of sediment. Our last category of rocks from the rock cycle are those rocks that have been altered in the earth by high heat and/or pressure - Metamorphic Rocks.

Unconformities
Unconformities are an important part of the stratigraphic record. They represent periods of non-deposition and erosion. Knowing how to interpret and identify unconformities can help a geologist piece together the history of the stratigraphic record, and how that sequence of rocks relates to other sequences.
