==Petroleum province==

'''Petroleum province''', a geographic term, is an area where petroleum occurs in commercial quantities. Basin is sometimes used geographically to mean petroleum province, such as the Williston Basin or Paris Basin. The Zagros fold belt could be a structural province or a petroleum province, not a basin.

'''Petroleum province''', a geographic term, is an area where petroleum occurs in commercial quantities. Basin is sometimes used geographically to mean petroleum province, such as the Williston Basin or Paris Basin. The Zagros [[fold]] belt could be a structural province or a petroleum province, not a basin.

A map showing differential thickness of sedimentary rocks is used to determine basins (thick), uplifts (thin), and fold belts (folded). These features are properly named provinces; if they contain petroleum, they are called petroleum provinces. The use of “basin” in this context is improper; it is also inconsistent with the [[petroleum system]] concept described below, which defines “basin” as the area into which sedimentary rocks are deposited.

A '''sedimentary basin''' is a depression filled with sedimentary rocks. The presence of sedimentary rocks is proof that a basin existed.

A '''sedimentary basin''' is a depression filled with sedimentary rocks. The presence of sedimentary rocks is proof that a basin existed.

The depression, formed by any tectonic process, is lined by '''[[basement]] rock''', which can be igneous, metamorphic, and/or sedimentary rock. The '''basin fill''' includes the rock matter, organic matter, and water deposited in this depression. In certain cases, such as with [[coal]] and some carbonate deposits, the sedimentary material is formed in situ. The essential elements of a petroleum system are deposited in sedimentary basins. Frequently, one or more overlapping sedimentary basins are responsible for the essential elements of a petroleum system. Traps are formed by tectonic processes that act on sedimentary rocks. However, the moment petroleum is generated, biologically or thermally, a petroleum system is formed.
