Astronomical cycle driving of coal-bearing rock system rotations in the Permian Shihezi Formation at Renlou Coal Mine

Solid Earth Sciences
Marine terrestrial transitional sedimentary rocks of Renlou Coal Mine are developed in coal bearing rock formations, which exhibits obvious cyclicity. These sedimentary cycles have a good correspondence with astronomical cycle signals.

Global Carbon Cycle Recorded in the Deep-sea Sediments and Milankovitch Cycle.

Journal of Geography (Chigaku Zasshi), 1995
Several hundred years of astronomical observations have left no doubt that the Earth's orbit is subject to cyclic variations. While the annual energy receipt of solar radiation over the Earth as a whole is not change, the distribution of this energy, by latitude and by season, is affected by three parameters: an obliquity cycle of 41kyr, an ...

Astronomically Forced Cyclicity and Cyclostratigraphic Framework of the Middle Jurassic Bath–Bajocian Formation in the West Siberian Basin

Applied Sciences
We aim to elucidate the sedimentary cyclicity of the Middle Jurassic Bath–Bajocian Formation in the northern S Oilfield of the West Siberian Basin, address the lack of high-resolution Milankovitch cycle research in this region, and support hydrocarbon ...

Analysis method and indicator optimization of astronomical cycles in lacustrine fine-grained sedimentary strata-a case study of the Es4 scs in well niuye 1, Dongying Sag, Jiyang Depression, Bohai Bay Basin

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Cyclostratigraphic division in fine-grained sedimentary strata provides a fundamental basis for oil and gas exploration in such deposits. With continued research, increasing complexity and variability in cyclostratigraphic indicators and analytical ...
