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.
