Cratonic basin (Intracratonic basin) None: A broad comparatively shallow basin formed far from the edge of a continental craton as a result of prolonged, broadly distributed but slow subsidence of the continental lithosphere relative to the surrounding area. They are sometimes referred to as intracratonic sag basins.
The Williston Basin is a large intracratonic sedimentary basin in eastern Montana, western North Dakota, South Dakota, southern Saskatchewan, and south-western Manitoba that is known for its rich deposits of petroleum and potash. The basin is a geologic structural basin but not a topographic depression; it is transected by the Missouri River ...

Examples of such basin classifications include intracratonic, rift, passive margin, strike-slip, forearc, backarc-marginal sea, fold and thrust belt, and foreland basins. Sedimentary basin analysis is largely conducted by two types of geologists who have slightly different goals and approaches.
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges.
SEDEX deposits are lead-zinc sulfide deposits formed in intracratonic rift basins by the submarine venting of hydrothermal fluids. These deposits are commonly stratiform, tabular - lenticular and are typically hosted in shale however, sedimentary rocks detrictics or even carbonates could be the host.
The Surat Basin is an intracratonic basin that covers a sizeable section of New South Wales and southern Queensland. It was formed by fluvial sedimentation of an intracratonic area which underwent sediment sag-loading in the Jurassic to Cretaceous.
[15]: [26] There are two basins the large South Permian Basin, and the smaller Northern Permian basin, which are east–west trending. The basins are separated by the Ringkøbing-Fyn system of highs. [1]: [47] The Viking Graben lies between the Shetland Platform and the Fenno-Scandian high. The Central Graben lies amid the Permian basins and ...
