The typical wells in Liaoxi Uplift were selected to conduct studies on high‐frequency sequences and their correspondences with the Milankovitch Cycles in Dongying Formation based on integrated analysis of wireline logs and sieve residue logs. The results

The solar radiation or insolation at a specific locality on the Earth's surface is determined by the distance of this point from the sun and by the angle with which the radiation hits the earth's surface.

South China provides exceptional and unique sedimentary archives of Earth's fundamental changes in Ediacaran time. However, the lack of robust geochronological constraints renders a poorly-defined chronostratigraphic framework for Ediacaran-aged strata ...

Milankovitch cycles in the Juniata Formation, Late Ordovician, Central Appalachian Basin, USA
Stratigraphy, 2016The Juniata Formation is a thick succession of prevalently red, cyclically bedded arenites, wackes, and mudrocks found in the Upper Ordovician of the Central Appalachian Basin, USA.

Milankovitch cycles in Neocene deep‐sea sediment
Paleoceanography, 1986Pelagic carbonate sediments from the world ocean basins commonly show cyclic variations in amount and/or degree of preservation of biogenic calcite, with periodicities of several tens to several hundreds of thousands of years. The direct causes of these cycles are fluctuations in noncarbonate dilution, carbonate production, carbonate dissolution, and ...

Filtering of Milankovitch Cycles by the Thermohaline Circulation
Journal of Climate, 1999A low-order, basin-averaged, coupled atmosphere‐ocean paleoclimate model is developed and the results from a 3.2-Myr model paleointegration described. A three-basin version of the Wright‐Stocker ocean model is used to compute the thermohaline circulation component of the climate system, with a six-basin energy balance atmosphere coupled to the ocean ...
