  1. 1. Record of the end-Triassic mass extinction in shallow marine carbonates: the Lorüns section (Austria)

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linus Brakebusch; [2022]
    Keywords : sedimentology; geochemistry; ooids; oolites; oncoids; oncolites; Triassic; Jurassic; Rhaetian; Hettangian; ocean acidification; Earth and Environmental Sciences;

    Abstract : The end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea.

  3. 2. Oolites from the Arabian platform: Archives for the aftermath of the end-Triassic mass extinction

    University essay from Lunds universitet/Geologiska institutionen

    Author : Johannes Greiff; [2021]
    Keywords : sedimentology; carbonates; geochemistry; oolites; ooids; thrombolites; microbialites; Triassic; Jurassic; Hettangian; extinction; United Arab Emirates; Wadi Ghalilah; Wadi Milaha; Earth and Environmental Sciences;

    Abstract : The end-Triassic mass extinction (ETME) which occurred around 201 Ma is known as one of “the big five” mass extinction events of the Phanerozoic eon. Its effects were most severe on marine ecosystems, resulting in a global decline of invertebrate taxa and the complete extinction of the conodonts. READ MORE

  4. 3. Stratigraphy, sedimentology and geophysical assessment of the early Silurian Halla and Klinteberg formations, Altajme core, Gotland, Sweden

    Abstract : Den mer än 700 m mäktiga lagerföljden på Gotland är erosionsresterna av vidsträckta karbonatplattformar som bildades i den Baltiska bassängen under silurperioden. Detta arbete fokuserar på stratigrafin och bergarterna i borrkärnan Tallbacken-1 som togs upp vid Stora Vede av Sveriges geologiska undersökning år 2006. READ MORE
