Petrology encompasses:
* Mineralogy: The study of the minerals that make up rocks.
* Petrography: The description and classification of rocks based on their mineral composition, texture, and structure.
* Petrogenesis: The study of how rocks form and evolve. This includes understanding the processes of magmatism, metamorphism, and weathering.
There are also sub-branches of Petrology, such as:
* Igneous Petrology: The study of igneous rocks (formed from cooled magma or lava).
* Sedimentary Petrology: The study of sedimentary rocks (formed from the accumulation and cementation of sediments).
* Metamorphic Petrology: The study of metamorphic rocks (formed when existing rocks are changed by heat, pressure, or fluids).
So, while the general term for the study of rocks is Petrology, there are specialized branches within this field that delve into the specific types of rocks and their origins.
