Adapted from Wikipedia · Adventurer experience
A geologic province is a part of Earth that has similar rocks and land shapes. These areas share features like the types of rocks and how the ground has moved.
Neighbors of a geologic province might look alike but are often different because of their past. Learning about these provinces helps scientists understand Earth's history and changes.
Geologic provinces by origin
Geologic provinces are big parts of Earth's surface that have 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.
