Cyclic Sedimentation Cycles

The cyclic sedimentation of the Barakar Formation was controlled by autocyclic process, which occurred due to the lateral migration of streams triggered by intrabasinal differential subsidence. In many instances, the clastic sediments issued from the laterally migrating rivers interrupted the sedimentation resulting in thinner cycles in areas ...

Aapg Datapagesarchives Abstract Cyclic Sedimentation

Vertical and lateral distribution of environmentally controlled facies within a deltaic mass are the result of the cyclic nature of sedimentation and delta growth. In the Mississippi River Deltaic Plain, cycles are determined primarily by the shifting point source of sediment supply and continuing active subsidence.

The controlling mechanism of Carboniferous cyclic

The Controlling Mechanism Of Carboniferous Cyclic

The Carboniferous cycles of sedimentation of Europe and North America are particularly well developed examples of a phenomenon which occurs throughout the geological column. The Carboniferous cycles are shown to be caused by sedimentation following an abrupt rise in sea level relative to the plane of deposition. Changes in sea level relative to the plane of deposition

Assessment of sedimentation cycle and depositional history

Assessment Of Sedimentation Cycle And Depositional History

In the cyclic sedimentation process, it is common to observe a sequence of strata with consistent repetition of alternating lithologies. However, the entire deposition process may also have a random component, which can be quantified by computing the entropy of the sedimentation process, and the concept of entropy can be applied to the Markov ...

Jan 28, 1994 Cyclical trends in sedimentation rate may be caused by the climatic effects of low-frequency orbital cycles. Carbonate bedding cycles in the Albian of Italy show probable eccentricity modulation at periods of about 100 and 400 ka, and 100-ka carbonate cycles show modulation at a period of about 400 ka.

Cyclic Sedimentation An Overview Sciencedirect Topics

Many a times, the cycles of short duration are found embedded within a longer cycles (cycle in cycle). Cyclic sedimentation has been documented in numerous sedimentary basins that led to the development of cyclostratigraphy ( Weedon, 2005 ) and there are many lines of evidence that relate those cycles to short-term (Milankovitch band) glacio-eustatic pulses ( Grammer et al.,

Feb 28, 2013 Cyclic or rhythmic sedimentation is an old stratigraphic problem that has received considerable attention in the past (Suess, 1888 Grabau, 1913 Wanless and Shepard, 1936 Wheeler and Murray, 1957 Wells, 1960 Merriam, 1964 Vella, 1965 Duff et al., 1967 Elam and Chuber, 1972 Schwarzacher, 1975), and remains today an unresolved controversial topic

Abstract. The well-known Carboniferous cyclothems of North America and Europe are discussed as examples to illustrate the great extent and lateral variation of sedimentary cycles. Very many other instances of cyclic sedimentation, in rocks of most ages, in many parts of the world, are also characterized by a more or less regular lateral migration of simultaneously existing

Cyclic Sedimentation

cyclic sedimentation A style of sedimentation where the sequence of sedimentary facies develops in a regular and repeated manner. The cycle of sediments may consist of two or more facies, and the cycles may be symmetrical or asymmetrical (e.g. A B C D,A B C Dor A B C D C B A,A B C D C B A.

The term cyclic sedimentation is generic and can be applied to any type or scale of repetitive sedimentation (Einsele et al., 1991 ). Conversely, the term cyclothem has a much more specific application. The concept has mostly been applied to stratigraphic successions of middle to late Pennsylvanian (upper Carboniferous) rocks that were deposited in cratonic basins of

Among the possible causes of cyclic sedimentation, episodic carbonate dissolution has been ruled out in favor of cli-matic fluctuations with a large range of periods. Such fluctuations are consistent with the great geographic extension shown by alternation controls and with the continuous spectrum of scales that characterizes limestone-marl cycles.

Cyclic Sedimentation In The Holkerian Middle

Studies of the Horton Limestone (Holkerian) on the Askrigg Block, involving quantitative analysis of thin sections taken throughout the sequence, indicate a cyclic character to the conditions of deposition of the limestone. Eight minor cycles have been identified in the top 78 metres of the Holkerian. These cycles are compared with those present in the overlying Kingsdale

Spectral analysis was applied to the upper Campanian to lower Maestrichtian cyclic sediments to examine the regularity of the cycles. Power spectra were calculated from time series using Walsh spectral analysis. The most predominant wavelengths of the color cycles are 34-41 cm and 71-84 cm. With an average sedimentation rate of

Late Paleozoic Cyclic Sedimentation In Southeastern

People studying and collecting sedimentary rocks, minerals, and fossils in eastern Nebraska often find that locating rock exposures can be difficult. Most of the rolling hills in the eastern sixth of the state are underlain by thick, interlayered, glacial deposits, loess (windblown silt), and alluvium (stream-deposited sediments) of very young geologic age (fig. 1). These sediments cover the ...
