The word "cyclothem" is therefore proposed to designate a series of beds deposited during a single sedimentary cycle of the type that prevailed during the Pennsylvanian period. (Weller, in Wanless and Weller, 1932, p. 1003.) Evidently, cyclothem filled a need because it was soon adopted and used by other geologists.Wave-dominated nearshore sedimentation and ‘forced’ regression: post-abandonment facies, Great Limestone Cyclothem, Stainmore, UK AINSWORTH, R.

The Niobrara Formation / ˌnaɪ.əˈbrærə /, also called the Niobrara Chalk, is a geologic formation in North America that was deposited between 87 and 82 million years ago during the Coniacian, Santonian, and Campanian stages of the Late Cretaceous.

Continued lithologic and paleontologic considerations of Kansas Upper Pennsylvanian megacyclothems more firmly establish the basic ascending sequence of: outside (nearshore) shale—middle (transgressive) limestone—core (offshore) shale—upper (regressive) limestone—outside (nearshore) shale, as representing a single transgressive-regressive sequence; this sequence is thus considered ...A cyclothem is a coal-bearing cyclic sequence of sedimentary rocks characteristic of western Pennsylvania. Cyclothems contain limestone and gray-green shale deposited when sea level was high, gradually changing upward through red shale deposited near the mouth of the delta into interbedded sandstone, shale, and coal deposited in the river and ...
