Chemostratigraphic characteristics of trace elements, biomarkers and clay mineralogy indicating environmental conditions within Aptian sediments of the Organyà Basin, North‐east Spain, prior to the onset of OAE 1a

Abstract Shifting palaeoceanographic and palaeoclimatic conditions together with fluctuating eustatic sea levels during the Early Cretaceous Aptian stage led to a globally widespread deposition of organic‐rich marine sediments designated Oceanic Anoxic Event 1a. Here a detailed lithostratigraphic an...
