A Bayesian astrochronology for the Cambrian first occurrence of trilobites in West Gondwana (Morocco) (2024)
Journal Article
Sinnesael, M., Millard, A. R., & Smith, M. R. (2024). A Bayesian astrochronology for the Cambrian first occurrence of trilobites in West Gondwana (Morocco). Geology, 52(3), 205-209. https://doi.org/10.1130/G51718.1

The first occurrence of trilobites ~520 million years ago is an iconic feature of the Cambrian Explosion. Developing a robust evolutionary view on early Cambrian life is generally hindered by large uncertainties in the ages of fossil finds, and their...

Ordovician cyclostratigraphy and astrochronology (2023)
Journal Article
Sinnesael, M. (2023). Ordovician cyclostratigraphy and astrochronology. Geological Society Special Publications, 532(1), https://doi.org/10.1144/sp532-2022-31

Cyclostratigraphy is an important tool for understanding astronomical climate forcing and reconstructing geological time in sedimentary sequences, provided that an imprint of insolation variations caused by Earth’s orbital eccentricity, obliquity and...

A new age model and chemostratigraphic framework for the Maastrichtian type area (southeastern Netherlands, northeastern Belgium) (2022)
Journal Article
Vellekoop, J., Kaskes, P., Sinnesael, M., Huygh, J., Déhais, T., Jagt, J. W., …Claeys, P. (2022). A new age model and chemostratigraphic framework for the Maastrichtian type area (southeastern Netherlands, northeastern Belgium). Newsletters on Stratigraphy, 55(4), 479-501. https://doi.org/10.1127/nos/2022/0703

The youngest time interval of the Cretaceous Period is known as the Maastrichtian, in reference to the shallow-marine strata outcropping in the area surrounding the city of Maastricht, in the Netherlands-Belgium border region. While the type-Maastric... Read More about A new age model and chemostratigraphic framework for the Maastrichtian type area (southeastern Netherlands, northeastern Belgium).

A decomposition approach to cyclostratigraphic signal processing (2021)
Journal Article
Wouters, S., Crucifix, M., Sinnesael, M., Da Silva, A., Zeeden, C., Zivanovic, M., …Devleeschouwer, X. (2022). A decomposition approach to cyclostratigraphic signal processing. Earth-Science Reviews, 225, Article 103894. https://doi.org/10.1016/j.earscirev.2021.103894

Sedimentary rocks can record signals produced by highly complex processes. These signals are generated by a progressive deposition of sediments which can be affected, mainly through the climate system, by regular astronomical cycles (i.e. Milankovitc...

Precession-driven climate cycles and time scale prior to the Hirnantian glacial maximum (2021)
Journal Article
Sinnesael, M., McLaughlin, P., Desrochers, A., Mauviel, A., De Weirdt, J., Claeys, P., & Vandenbroucke, T. (2021). Precession-driven climate cycles and time scale prior to the Hirnantian glacial maximum. Geology, 49(11), 1295-1300. https://doi.org/10.1130/g49083.1

Paleozoic astrochronologies are limited by uncertainties in past astronomical configurations and the availability of complete stratigraphic sections with precise, independent age control. We show it is possible to reconstruct a robust Paleozoic ~104-... Read More about Precession-driven climate cycles and time scale prior to the Hirnantian glacial maximum.

Detecting initial aragonite and calcite variations in limestone–marl alternations (2021)
Journal Article
Nohl, T., Steinbauer, M. J., Sinnesael, M., & Jarochowska, E. (2021). Detecting initial aragonite and calcite variations in limestone–marl alternations. Sedimentology, 68(7), 3102-3115. https://doi.org/10.1111/sed.12885

Limestone–marl alternations are commonly used for high-resolution cyclostratigraphic studies and palaeoenvironmental reconstructions, but diagenetic studies indicate that not all limestone–marl alternations reflect genuine differences in the initial...

Globally distributed iridium layer preserved within the Chicxulub impact structure (2021)
Journal Article
Goderis, S., Sato, H., Ferrière, L., Schmitz, B., Burney, D., Kaskes, P., …Whalen, M. T. (2021). Globally distributed iridium layer preserved within the Chicxulub impact structure. Science Advances, 7(9), Article eabe3647. https://doi.org/10.1126/sciadv.abe3647

The Cretaceous-Paleogene (K-Pg) mass extinction is marked globally by elevated concentrations of iridium, emplaced by a hypervelocity impact event 66 million years ago. Here, we report new data from four independent laboratories that reveal a positiv... Read More about Globally distributed iridium layer preserved within the Chicxulub impact structure.

Anchoring the Late Devonian mass extinction in absolute time by integrating climatic controls and radio-isotopic dating (2020)
Journal Article

The Devonian Frasnian–Famennian (F–F) boundary marks one of the five main extinction intervals of the Phanerozoic Aeon. This time was characterized by two pulses of oceanic anoxia, named the Lower and Upper Kellwasser events, during which massive mar...
