The Depositional Record, Volume 12, Issue 2, April 2026.During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...

Conodonts in Ordovician Chronostratigraphy
, 2015 The great importance of conodonts in Ordovician chronostratigraphy is shown by the fact that conodonts are used for the definition of two of the seven global stages, and seven of the 18 stage slices, now recognized within this ...

Calcareous nannofossil biostratigraphy: historical background and application in Cenozoic chronostratigraphy [PDF]
, 2017 Calcareous nannofossils are considered one of the most powerful biostratigraphical tool in marine carbonate sediments especially in open ocean settings. Their origination goes at least as far back as the Triassic (ca.
