A geologic province is a spatial entity with common geologic attributes. A province may include a single dominant structural element such as a basin or a fold belt, or a number of contiguous related elements. Adjoining provinces may be similar in structure but be considered separate due to differing histories.
There are several meanings of geologic provinces used in specific contexts.
In geography, a shield is a large Archaean (Precambrian) rock mass at the centre of a continent, for example the Canadian Shield and Baltic Shield. ... A craton is an old and stable part of the continental crust that has survived the merging and splitting of continents and supercontinents for at least 500 million years. ... Volcanic rock on North America Plutonic rock on North America Igneous rocks are formed when molten rock (magma) cools and solidifies, with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. ... In geology, a crust is the outer layer of a planet, part of its lithosphere. ...

Some studies classify provinces based upon mineral resources, such as mineral deposits. There are a particularly large number of provinces identified worldwide for petroleum and other mineral fuels. Minerals are natural compounds formed through geological processes. ... Nodding donkey pumping an oil well near Sarnia, Ontario, 2001 Petroleum (from Greek petra – rock and oleum – oil), crude oil, sometimes colloquially called black gold, is a thick, dark brown or greenish flammable liquid, which exists in the upper strata of some areas of the Earths crust. ... Coal rail cars in Ashtabula, Ohio Fossil fuels, also known as mineral fuels, are hydrocarbon-containing natural resources such as coal, petroleum and natural gas. ...
The Valley and Ridge is the westernmost physiographic province of the Appalachian Mountains, bounded to the east by the Blue Ridge, the south by the Piedmont, and the northwest by the Appalachian Plateau.
The province owes its topography to the erosion of alternating layers of hard and soft sedimentary rock that were folded and faulted during the building of the Appalachians.
geologic division between the Blue Ridge and Piedmont provinces is precisely limited by the outcrop of the Cartersville and Great Smoky faults that separate sedimentary rocks in the northwest from metamorphic rocks in the southeast.
In modern languages, a province is a secondary level of government in many countries, while other use alternative terms for similar entities, such as state (in Australia, Brazil, India, Mexico and the United States), land (in Austria, Germany), department (in Bolivia, Uruguay), or prefecture (in Japan).
In geology the term province refers to a specific physiogeographic area composed of a grouping of like bathymetric or former bathymetric elements (now sedimentary strata above water) whose features are in obvious contrast to the surrounding regions, or other provinces.
In Peru, provinces are a tertiary unit of government, as the country is divided into twenty-five regions, which are then subdivided into 194 provinces.
