• Source: Outline of geology

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.

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



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 – The region between an oceanic trench and the 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
