A cyclothem is a repeated sequence of sedimentary rock layers composed of alternating beds of limestone and shale, indicating changes in sea level and climate over geological time. The likely cause of cyclothem patterns is cyclical changes in sea level caused by tectonic activity and variations in Earth's orbit and axial tilt, leading to ..."Flint" is the official gemstone of Ohio. Flint is actually called chert (the two terms are synonymous, despite what anyone else might say), a cryptocrystalline, quartzose sedimentary rock. High-quality, colorful, multicolored, and multipatterned flint is moderately common at certain Ohio localities. A couple famous flint occurrences in east-central Ohio include the Vanport Flint at ...

The Manning Canyon Formation is an exemplar of one end of the spectrum of cyclothem successions (Fielding, 2021), in which coarse clastic sediment is a minor constituent of cycles. Such cycles are typically carbonate and mudrock-dominated, but preserve evidence for subaerial emergence in the form of paleosols.

Climate change refers to significant changes in global temperature, precipitation, wind patterns and other measures of climate that occur over several decades or longer. The seas are rising. The foods we eat and take for granted are threatened. Ocean acidification is increasing. Ecosystems are changing, and for some, that could spell the end of certain regions the way we have known them.

Because peritidal accommodation cycles begin and end with the sediment surface at sea level, the expected cycle period can be estimated by finding the time span at which accommodation and accumulation rates balance. The maximum duration of the hiatus is the time span at which rates of …Pennsylvanian continental cyclothem development: no evidence of direct climatic control in the Upper Freeport Formation (Allegheny Group) of Pennsylvania (northern Appalachian Basin) Blas L.
