Along the base of the Rocky Mountains, and eastward for many miles, the basin of the Arkansas river is occupied by Cretaceous rocks. At bottom are the Dakota sandstones, several hundred feet in thickness; and above these a great body of shales, constituting the Benton, Niobrara and Pierre groups and having a total thickness of 3900 feet. In the main these shales are argillaceous; but at a few horizons they are calcareous, and at one level a sandstone appears, accompanied by a few feet of…

The cyclothemic sedimentary motifs described from Wanganui provide invaluable insights for the interpretation of other Phanerozoic glacio–eustatic successions such as those of Permo–Carboniferous and Ordovician age.
Interregional model for deposition of Upper Cretaceous pelagic rhythmites, U.S. Western Interior
The Bridge Creek Member of the Greenhorn Limestone and Fort Hays Member of the Niobrara Chalk comprise rhythmic sequences of bioturbated pelagic limestone or chalk beds that alternate with generally
"Geologic Time" As Calculated By C. D. Walcott
In 1893, Walcott contributed to the debate on the length of geologic time. He approached the problem by calculating average thickness of the Paleozoic rock column in the west and dividing by rates of
Integrated stratigraphy and palaeoenvironment of the Cenomanian-Lower Turonian (Upper Cretaceous) of northern Westphalia, North Germany
SummaryThe present study provides an integrated stratigraphy of the Lower Cenomanian-Lower Turonian of the northwestern Münsterland Basin, Westphalia. This is important to establish a standard
Cyclostratigraphy of Shallow-Marine Carbonates – Limitations and Opportunities
Lithological expression of Milankovitch cyclicity in carbonate-dominated, pelagic, Barremian deposits in central Italy
Abstract In continuous sedimentary sequences, cyclostratigraphy can provide good time control on the duration of stratigraphic stages and palaeomagnetic chrons. This approach has been applied to the
Regional and global stratigraphic cycles
One of the achievements of modern sedimentology has been to demonstrate the almost ubiquitous presence of major lateral facies changes in sedimentary rocks, with the result that nobody uses
