Resumen:
The carbon-isotope composition of organic matter and carbonate in terrestrial and marine sediments from the Early Toarcian was subject to abrupt disturbances of the Carbon cycle, recognized as a negative carbon isotope excursion (CIE) disrupting an overall positive excursion. We present new data from Arroyo Lapa and Arroyo Serrucho, comprising high-resolution lithostratigraphy, biostratigraphy, organic carbon isotopes (bulk sediment and fossil wood), total organic carbon, hydrogen index and new ages of ash beds from the Early Toarcian.
