Combined Magnetostratigraphy From Three Localities of the Rainstorm Member of the Johnnie Formation in California and Nevada, United States Calibrated by Cyclostratigraphy: A 13 R/Ma Reversal Frequency for the Ediacaran [PDF]

open access: goldFrontiers in Earth Science, 2021
A combined magnetostratigraphy for the Rainstorm Member of the Ediacaran Johnnie Formation was constructed using the sediment accumulation rates determined by rock magnetic cyclostratigraphy for three localities of the Rainstorm Member to provide a high ...

Cyclostratigraphy of Lower Permian alkaline lacustrine deposits in the Mahu Sag, Junggar basin and its stratigraphic implication [PDF]

open access: goldFrontiers in Earth Science, 2023
The Lower Permian Fengcheng Formation of the Mahu Sag is one of the most potentially petroliferous sequences in China, and its unique alkaline lacustrine deposits provide important information on the paleoclimate and paleoenvironment of the early Permian.

Cyclostratigraphy and astrochronology: Case studies from China. [PDF]

open access: yesPalaeogeogr Palaeoclimatol Palaeoecol, 2020
A high-precision geologic time scale is the essential key for understanding the Earth's evolutionary history and geologic processes. Astronomical tuning of orbitally forced stratigraphic records to construct high-resolution Astronomical Time Scales (ATS) has led to a progressive refinement of the geologic time scale over the past two decades.

Initial Results of the Cyclostratigraphy Intercomparison Project 2

open access: gold
The study of astronomical climate forcing and the application of cyclostratigraphy grew spectacularly over the last decades. In cyclostratigraphy a wide range in methods are used to assess cyclicity and orbitally forced cyclicity. However, comparative studies between these different approaches remain too rare.

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]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2020
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]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2020
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.
