Adapted from Wikipedia · Discoverer experience
A geologic province is an area of the Earth that shares similar geological features. These features can include things like rock types, layers, and how the land has moved over time. A province might have one main structure, like a basin or a fold belt, or it might have many related structures that are close together.
Neighbors of a geologic province might look similar but are often treated as separate because they have different histories. Understanding these provinces helps scientists learn about the Earth's past and how it has changed.
Geologic provinces by origin
Geologic provinces are large areas of Earth's surface that share similar geological features. These areas can include things like basins or fold belts. Even if nearby provinces look alike, they might have different histories, making them separate provinces.
| Province | Definition | Subcategories | Examples |
|---|---|---|---|
| Shield | Exposed Precambrian crystalline igneous and metamorphic rocks that form tectonically stable areas | ||
| Platform | Horizontal or gently-lying sedimentary strata covering a basement of igneous or metamorphic rocks | ||
| Orogen | Linear or arc-shaped formation where continental crust has been folded, deformed and uplifted to form mountain ranges | ||
| Basin | Low-lying formation of rock strata formed by tectonic warping of previously horizontal strata | ||
| Large igneous province | Accumulation of igneous rocks, including liquid rock (intrusive) or volcanic rock formations (extrusive) | ||
| Extended crust | Continental crust thinned due to extensional strain |
Geologic provinces by resources
Some studies group areas called provinces based on the minerals found there, like oil and other fuels. One example is the Niger Delta petroleum province.
