Short summary
An abrupt increase in seasonal precipitation during the PETM in the Pyrenean Gulf has been proposed, based on the occurrence of extensive fine-grained siliciclastic deposits. This paper provides evidence that coarse-grained siliciclastics were also delivered, indicative of episodes of intense rainy intervals in an otherwise semiarid PETM climate. Further, evidence is presented that PETM kaolinites were most likely resedimented from Cretaceous lateritic profiles developed in the basement.
