Milankovitch Period Uncertainties and Their Impact On Cyclostratigraphy [PDF]

open access: yes, 2015
Astronomically calibrated cyclostratigraphy relies on correct matching of observed sedimentary cycles to predicted astronomical drivers such as eccentricity, obliquity and climate-precession. However the periods of these astronomical cycles, in the past,

Milankovitch forcing of equilibrium ground-ice on Mars

Icarus (New York, N.Y. 1962), 2022
Summary Exchangeable ice deposits are present today on Mars in polar caps and as shallow subsurface mid-latitude ground-ice. Geologic evidence indicates these reservoirs waxed and waned in the past in concert with the emplacement and loss of equatorial ...

Mechanisms of Preservation of the Eccentricity and Longer-term Milankovitch Cycles in Detrital Supply and Carbonate Production in Hemipelagic Marl-Limestone Alternations

open access: yes, 2018
International audienceEccentricity cycles often exert a strong influence on sedimentary series, while they only have weak powers in the insolation series. Three case studies previously published in Early Cretaceous hemipelagic marl-limestone alternations
