The Permian System contains a great number and diversity of depositional sequences (Fig. 1) which illustrate sedimentary responses to a series of sealevel fluctuations. These sea-level fluctuations had many different amplitudes and durations, and were accompanied by a wide spectrum of rates of deposition (Fig. 2).

Stratigraphy and sequence stratigraphy of the Moscovian in the Donets basin
Tectonophysics, 1996New results are presented on the stratigraphy based on Fusulinids and Palynomorphs and the sequence stratigraphy of the Moscovian in the Donets basin. They have been developed by comparison of our observations on cross-sections near Artemovsk and the published coal mine logs of Artemovsk Geological Survey.

Carbonate Sequence Stratigraphy
1988Abstract Derived from the 1991 Research Symposium on Carbonate Sequence Stratigraphy, the authors have brought together in one volume a representative sampling of pivotal research in this important topic. Its three sections describe (1) sequence concepts and sedimentologic principles, (2) seismic sequence case studies involving seismic ...

Arenite Petrography in Sequence Stratigraphy
The Journal of Geology, 1995Stratigraphic boundary surfaces and internal anatomy of unconformity-bounded units may be deciphered by using properly conceived petrography that identifies compositional, spatial, and temporal characteristics of sand grains. Discussion of two case studies of synorogenic deep marine successions indicates the potential of this method.

Glaciodynamic sequence stratigraphy
Geological Society, London, Special Publications, 2012Abstract The glaciofluvial deposits are by volume and permeability the most important unit in the terrestrial glacial successions, and they are the obvious target for groundwater as well as hydrocarbon reservoir exploration. The dominant glaciofluvial units are related to the proglacial setting in the foreland of an advancing ice margin ...

1997
One of the features of the existing geological time scale about which Vail et al. (1977) expressed concern is that “the boundaries of the global cycles in several cases do not match the standard epoch and period boundaries.” The cycles in the Exxon global cycle chart are bounded by unconformities, and traditional stratigraphic methods also made use of ...

Sequence stratigraphy of carbonate rocks
The Leading Edge, 1999In the first contribution to TLE’s Geologic Column, J. M. Mulholland concluded that “sequence stratigraphy … is a tool that every explorationist must master.” I agree. In fact, sequence stratigraphy is more than a versatile tool in exploration and production geology. It is in many ways a role model for applied earth sciences.

Carbon isotopes and sequence stratigraphy
Geological Society, London, Special Publications, 1996Abstract The carbon isotope (δ 13 C) stratigraphy of the late Lower Cenomanian to early Lower Turonian is presented for three sections (Folkestone in the Anglo-Paris Basin, Wünstorf in the Lower Saxony Basin and Speeton in the Cleveland Basin). The similarity between these isotope curves suggests that they

Forty years of sequence stratigraphy
Geological Society of America Bulletin, 1988The principles and practice of sequence stratigraphy are of ancient heritage. In North America, the separation of the Carboniferous into two systems and the identification of Ozarkian and Comanchean and other indigenous chronostratigraphic entities were efforts toward making the segmentation of the geologic column more representative of stratigraphic ...
