Geochemical response of Aptian sediments before, during and after Oceanic Anoxic Event 1A: insight from the La Frontera section Subbetic Basin, southern Spain
The hallmark of lower Aptian sediments is commonly organic-rich black shales related to widespread oxygen deficient conditions known as ocean anoxic event 1a (OAE1a). The La Frontera section, located in the Subbetic Basin, southern Spain, documents the response to OAE1a within a ∼28 m interval divid...
