On the peritidal cycles and their diagenetic evolution in the Lower Jurassic carbonates of the Calcare Massiccio Formation (Central Apennines)

Geologica Carpathica, 2015
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.

REPRODUCIBILITY IN CYCLOSTRATIGRAPHY: INITIATING AN INTERCOMPARISON PROJECT

Geological Society of America Abstracts with Programs, 2017
The study of astronomical climate forcing and the application of cyclostratigraphy have experienced a spectacular growth over the last decades. In the field of cyclostratigraphy a broad range in methodological approaches exist. However, comparative study between the different approaches is lacking.

A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior. However, the geomagnetic reversal pattern during the Ediacaran–Cambrian transition remains elusive. Here we present an integrated magneto‐ and cyclo‐stratigraphic study of a ∼1.8‐Myr‐long, late

Nonmarine time-stratigraphy in a rift setting: An example from the Mid-Permian lower Quanzijie low-order cycle Bogda Mountains, NW China

Journal of Palaeogeography, 2015
Sedimentological and stratigraphic studies of seven stratigraphic sections of Permian Hongyanchi (HYC) and Quanzijie (QZJ) low-order cycles (LCs) in the Tarlong-Taodonggou half graben and Dalongkou area in Bogda Mountains, NW China, demonstrate effective

Disentangling Continental Weathering During the Late Paleozoic Ice Age

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The consumption of atmospheric CO2 through continental weathering played a critical role in shaping the evolution of the late Paleozoic Ice Age (LPIA), presumably driven by the Hercynian orogeny and the evolution of terrestrial plants. However, the relative impacts of these two major drivers to continental weathering remain poorly constrained.

Toward a Robust Plio‐Pleistocene Chronostratigraphy for ODP Site 762

Geophysical Research Letters, 2020
The advent of rapidly acquired proxy records provides paleoceanographers and paleoclimatologists with a wealth of high‐resolution data. These data are a boon for the community, as they enable millennial or even submillennial scale interpretation of past ...

Reconstructing Early Cenozoic Paleodrainage and Tectonic Evolution in the Southeastern Tibetan Plateau: Evidence From Detrital Zircon and Tourmaline Provenance

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Paleogene sedimentary basins of southeastern Tibet record sediment dispersal patterns associated with crustal deformation during the early stages of the India–Asia collision. We present detrital zircon U–Pb geochronology, tourmaline geochemistry, and petrographic data from the Gonjo and Mangkang basins that suggest a reginal interconnected

Resolving allogenic forcings on shallow‐marine sedimentary archives of the Taiwan Western Foreland Basin

Sedimentology, Volume 72, Issue 6, Page 1755-1785, October 2025.
ABSTRACT An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation ...

Industrial Gamma Radiation Signals: An Untapped Resource to Reconstruct Neogene Paleoclimate Off Northwest Australia

Paleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Paleoceanographic reconstructions require both high‐resolution temporal records and high‐density spatial coverage. Scientific drilling provides detailed paleoclimate time‐series, but its spatial distribution limits our ability to capture regional climate dynamics.
