The following outline is provided as an overview of and topical guide to geology:
Geology – one of the Earth sciences – is the study of the Earth, with the general exclusion of present-day life, flow within the ocean, and the atmosphere. The field of geology encompasses the composition, structure, physical properties, and history of Earth's components, and the processes by which it is shaped. Geologists typically study rock, sediment, soil, rivers, and natural resources.
Branches of geology
Geology applies primarily to Earth, but can be applied to any planet or extraterrestrial body.
Geology of Earth
Subdisciplines of geology:
- Biogeology – Study of the interactions between the Earth's biosphere and the lithosphere
- Economic geology – Science concerned with earth materials of economic value
- Engineering geology – Application of geology to engineering practice
- Environmental geology – Science of the practical application of geology in environmental problems.
- Geochemistry – Science that applies chemistry to analyze geological systems
- Geologic modelling – Applied science of creating computerized representations of portions of the Earth's crust
- Geomorphology – Scientific study of landforms
- Geophysics – Physics of the Earth and its vicinity
- Historical geology – Study of the geological history of Earth
- Hydrogeology – Study of the distribution and movement of groundwater
- Marine geology – Study of the history and structure of the ocean floor
- Mineralogy – Scientific study of minerals and mineralised artifacts
- Mining geology – Extraction of valuable minerals or other geological materials from the Earth
- Paleontology – Study of life before the Holocene epoch
- Petroleum geology – Study of the origin, occurrence, movement, accumulation, and exploration of hydrocarbon fuels
- Petrology – Branch of geology that studies the formation, composition, distribution and structure of rocks
- Sedimentology – Study of natural sediments and their formation processes
- Stratigraphy – Study of rock layers and their formation
- Structural geology – Science of the description and interpretation of deformation in the Earth's crust
- Volcanology – Study of volcanoes

Principles of geology
- Principle of cross-cutting relationships – Principle that the geologic feature which cuts another is the younger of the two
- Law of included fragments – Clasts in a rock are older than the rock formation
- Principle of uniformitarianism – Assumption that the natural laws and processes of the universe are constant through time and space
- Principle of original horizontality – Layers of sediment are deposited approximately horizontally under the action of gravity
- Principle of superposition – Law stating that newer strata stack above older ones
- Principle of faunal succession – Concept in geology
Geological processes
- Petrogenesis – Processes that form rock

Geologic provinces
Oceanic crust 0–20 Ma 20–65 Ma >65 Ma Geologic provinces Shield Platform Orogen Basin Large igneous province Extended crust
Geologic province – Spatial entity with common geologic attributes
Geologic provinces based on origin:
- Shield – Large stable area of exposed Precambrian crystalline rock
- Platform – A continental area covered by relatively flat or gently tilted, mainly sedimentary strata
- Orogen – Zone affected by mountain formationPages displaying short descriptions of redirect targets
- Island arc – Arc-shaped archipelago formed by intense seismic activity of long chains of active volcanoes
- Continental arc – Type of volcanic arc occurring along a continental margin
- Forearc – Region between an oceanic trench and associated volcanic arc
- Oceanic basin – Geologic basin under the sea
- Cratonic basin – Old and stable part of the continental lithosphere
- Foreland basin, also known as foredeep basin – Structural basin that develops adjacent and parallel to a mountain belt
- Large igneous province – Huge regional accumulation of igneous rocks
- Extended crust – Outermost solid shell of astronomical bodies
- Rift – Geological linear zone where the lithosphere is being pulled apart
Plate tectonics
- Plate tectonics – Movement of Earth's lithosphere
