Turbidite‐induced re‐oxygenation episodes of the sediment‐water interface in a diverticulum of the Tethys Ocean during the Oceanic Anoxic Event 1a: The French Vocontian Basin

open access: yesThe Depositional Record, Volume 6, Issue 2, Page 352-382, June 2020., 2020
The oceanic anoxic event OAE1a episode has been recorded in the Vocontian Basin (SE‐France) but recurrent reworking (turbidites) altered the record. Abstract Widespread anoxic events affected the Tethys Ocean during the Mesozoic. The Ocean Anoxic Event 1a (Early Aptian), expressed as the Selli Level or Goguel Level (GL) in European basins.
