The Mid-Ludfordian (late Silurian) Glaciation: a link with global changes in ocean chemistry and ecosystem overturns
Original language description
The present study reviews the main geochemical, sedimentological, and paleontological events associated with one of the largest perturbations in the Phanerozoic carbon cycle, the Mid-Ludfordian Carbon Isotope Excursion (MLCIE), which is globally documented in late Silurian marine successions. Climate changes associated with the MLCIE are not yet well documented in contrast to most other Silurian CIEs. We report seawater surface temperature changes across the entire MLCIE using d18Oapatite records of conodonts originating from different regions located in temperate as well as tropical paleolatitudes. Significant positive d18Oapatite excursions (up to 3,8 permile) measured in temperate-water areas of the Prague Basin and Carnic Alps (peri-Gondwana) as well as in the tropical areas of Baltica (Laurussia) and Australia (Gondwana) provide evidence for significant global cooling during the MLCIE. The marked cooling of sea surface temperatures, coupled with a significant eustatic sea-level fall recorded on
