On the peritidal cycles and their diagenetic evolution in the Lower Jurassic carbonates of the Calcare Massiccio Formation (Central Apennines) [PDF]
This paper shows the environmental changes and high-frequency cyclicity recorded by Lower Jurassic shallow-water carbonates known as the Calcare Massiccio Formation which crop out in the central Apennines of Italy.

Milankovitch Period Uncertainties and Their Impact On Cyclostratigraphy [PDF]
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,

Comparison of variations in sediment accumulation rates of the upper part of Zakeen Formation through cyclostratigraphic study in 2SK-1 and 2SKD-1 wells in Salman gas field [PDF]
The Zakeen Formation is one of the possible gas reservoirs in the Zagros sedimentary basin. In this paper, the cyclostratigraphic study of the upper part of the Zakeen Formation was performed by using evolutionary spectral analysis methods.

A hundred years of Milutin Milankovic's climate change theory-geological implications [PDF]
Milanković’s cycles theory published hundred years ago is the most important theory in climate science and had great influence on Earth disciplines. Nevertheless, his work waited for more than fifty years for confirmation.
