- "Petrology is the branch of geology that studies rocks and the conditions under which they form."
The study of rocks, their formation, structure, and properties.
Minerals: Study of the physical and chemical properties of minerals and their relationships with each other.
Igneous Rocks: Study of the formation, classification, and mineralogy of rocks that solidify from molten magma or lava.
Sedimentary Rocks: Study of the formation, classification, and properties of rocks that are deposited and lithified at the Earth's surface.
Metamorphic Rocks: Study of the formation, classification, and mineralogy of rocks that have been altered by heat, pressure, and/or fluids.
Volcanology: Study of the processes and products of volcanic eruptions and their impact on the environment.
Petrogenesis: Study of the origin and evolution of rocks and their relationship to tectonic processes.
Geochemistry: Study of the chemical composition and behavior of rocks and minerals, and their interaction with the environment.
Field Work: Study of rocks and their geological features in their natural setting, including mapping, sample collection, and analysis.
Optical Mineralogy: Study of the properties of minerals as viewed under a microscope, including crystal structure and optical properties.
X-ray Diffraction: Study of the crystal structure and composition of rocks and minerals using X-rays.
- "Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology."
- "Igneous and metamorphic petrology are commonly taught together because both make heavy use of chemistry, chemical methods, and phase diagrams."
- "Sedimentary petrology is commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock."
- "Modern sedimentary petrology is making increasing use of chemistry."
- "Petrology (from Ancient Greek πέτρος (pétros) 'rock', and -λογία (-logía) 'study of')..."
