The Mulde event was a secundo-secundo event,[1] and marked the second of three1 relatively minor mass extinctions during the Silurian period. It coincided with a global drop in sea level, and is closely followed by an excursion in geochemical isotopes. Its onset is synchronous with the deposition of the Fröel formation in Gotland.[1]
^1 The Ireviken event and Lau event, other late Silurian extinction events, were both closely followed by isotopic excursions, as was the Mulde event.
