The meeting will bring together cyclostratigraphers and researchers from adjacent fields to discuss methodology, uncertainty, and reproducibility in cyclostratigraphy. The meeting is supported by the Research Foundation Flanders (FWO, grant no. W00522N).

Registration fees

Fees include lunches, coffee breaks and dinner on Thursday:

  • Early Career Researchers (Masters and PhD students): 80 EUR
  • Senior researchers: 150 EUR
  • Hybrid participation: free, but registration is still required

  • Age-depth modeling in R led by Niklas Hohmann and David De Vleeschouwer
  • FAIR code and data led by Ilja Kocken

Thursday 26th afternoon

Keynotes on methodology, uncertainty, and reproducibility in cyclostratigraphy. Keynote speakers:

Saturday 28th & Sunday 29th

Field trip led by Anne-Christine Da Silva and David De Vleeschouwer. Participation fee: 200 EUR, including transport from Utrecht and back, hotel with breakfast and field lunch.

The target of the field trip is to visit Devonian and Carboniferous outcrops with a target on cyclostratigraphy:

  • Chanxhe – Uppermost Famennian, Hangenberg black shale event, Devonian-Carboniferous boundary and Lowermost Carboniferous – Mass extinction and astronomical forcing.
  • Rivage – Lowermost Carboniferous – cycles and carbonate platform drowning
  • Heid des Gattes (Aywaille) - Famennian tidal rhythmites
  • Lustin Formation (Aywaille) - Frasnian carbonate platform
  • Ninglinspo -  Unconformity at the northwestern border of the Lower Palaeozoic Stavelot-Venn basement. Lochkovian basal conglomerate and reddish claystones, unconformably lying on Cambrian slates. The Wilson cycle at its best!
  • Sallet - Carboniferous cyclicity

Venue

The meeting will take place at the Department of Earth Sciences at Utrecht Science Park, the science campus of Utrecht ľ¹Ï¸£ÀûÓ°ÊÓ. The address: Vening Meineszgebouw A, Princetonlaan 8a, 3584 CB Utrecht.
