Article Type: Meeting abstract

Abstract:

Most of the major hydrocarbon accumulations are in basins formed during the Mesozoic and the Cenozoic. Many of these basins, their contained sediments, and their structural and stratigraphically trapped oil and gas fields appear to be genetically related to the hypotheses of Previous HitplateNext Hit Previous HittectonicsNext Hit.

Of particular interest are those basins that formed at Previous HitplateNext Hit boundaries. Three fundamental methods of basin development according to type of Previous HitplateNext Hit-margin deformation are reviewed: tensional, compressional, and shear-zone. Basin types, structural styles, and sedimentary histories are reviewed for different Previous HitplateNext Hit margins.

Significant intracratonic basins have developed as a result of shear-zones "cracking" the cratons. Furthermore, important intracratonic "stand-still" basins and their associated uplifts have resulted from viscosity inhomogeneities within the asthenosphere.

Many major worldwide eustatic changes in sea level appear to be the result of the episodic nature of sea-floor spreading. Accordingly, much of the paleogeographic history of continents appears to be related to the hypotheses of Previous HitplateNext Hit Previous HittectonicsTop.
