Cratonic sequence

Cratonic sequences were first proposed by Laurence L. Sloss in 1963. [1] Each one represents a time when inland seas deposited sediments across the craton. The top and bottom edges of a sequence are each bounded by craton-wide unconformities (time gaps in the rock record). The unconformities indicate when the seas receded and sediment was ....

These interregional unconformities subdivide the cratonic stratigraphic column into six sequences—major rock-stratigraphic units (of higher than group, megagroup, or …Mesozoic Era, second of Earth's three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for "middle life." The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era.(See the geologic time scale.)The major divisions of the Mesozoic Era are, from oldest to ...Sedimentary controls on the sequence stratigraphic architecture in intra-cratonic basins: An example from the Lower Permian Shanxi Formation, Ordos Basin, northern China

Eustasy can generate sequences and unconformities, but it cannot tilt rocks, and yet observation of cratonic strata shows large-wavelength tilting and the resulting patterns of erosion. However, comparing the chronostratigraphic diagram from Case 5 (Fig. 7B) with the chronostratigraphic diagram from 1 (Fig. 5) shows a discrepancy in the pattern ...New data from detailed measured sections permit comprehensive analysis of the sequence framework of the Furongian (Upper Cambrian; Jiangshanian and Sunwaptan stages) Tunnel City Group (Lone Rock Formation and Mazomanie Formation) of Wisconsin and Minnesota.

The Tippecanoe sequence was the cratonic sequence--that is, the marine transgression--that followed the Sauk sequence; it extended from roughly the middle Ordovician to the early Devonian.. edimentary characteristics. After the regression of the Sauk Sea early in the Ordovician, the exposed craton for a time underwent vigorous …The sequence of poles displayed in a map (or on a globe surface) defines the ...

A cratonic sequence in geology is a very large-scale lithostratigraphic sequence in the rock record that represents a complete cycle of marine transgression …A cratonic sequence of strata is recognized by transgressive facies followed by regressive facies. Cratons are stable, ancient regions of the Earth's continental crust that have undergone minimal tectonic activity for millions of years. The sedimentary rocks found within cratons often exhibit distinct sequences of deposition known as cratonic ...A set of things next to each other in a set order; a series.

A series of musical phrases where a theme or melody is repeated, with some change each time, such as in pitch or length (example: opening of Beethoven's Fifth Symphony ).

The Sauk sequence was the earliest of the six cratonic sequences that have occurred during the Phanerozoic (followed by the Tippecanoe, Kaskaskia, Absaroka, Zuñi, and Tejas). It dates from the late Proterozoic through the early Ordovician, though the marine transgression did not begin in earnest until the middle Cambrian.ability for reproduction and metabolism.

The Precambrian Peninsular India is comprised of a few ancient cratonic nuclei that were formed during prolonged geological history during Archean to Paleoproterozoic and are classified into two blocks: The North Indian Block (NIB) and the South Indian block (SIB) (Naqvi and Rogers 1987).The former comprises of the Bundelkhand and Aravalli Cratons and the latter is made up of the Dharwar ...cratonic sequences.

These islands were present during the Sauk sequence, the earliest cratonic sequence. As a result of the Sauk sequence, epeiric seas covered most of North America, leaving only the craton of the Canadian Shield and the Transcontinental Arch islands exposed.The sedimentary rock record of the North American craton can be divided into six cratonic sequences.
