1. Record of the end-Triassic mass extinction in shallow marine carbonates: the Lorüns section (Austria)
University essay from Lunds universitet/Geologiska institutionenAbstract : 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.

2. Oolites from the Arabian platform: Archives for the aftermath of the end-Triassic mass extinction
University essay from Lunds universitet/Geologiska institutionenAbstract : 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

3. Sedimentary Factories and Ecosystem Change in the Triassic-Jurassic Boundary Interval : Insights from the Skåne Area (Southern Sweden)
University essay from Uppsala universitet/PaleobiologiAbstract : The End-Triassic Extinction (ETE) has long remained one of the lesser known among the so-called “Big Five”. There exist several hypotheses regarding the probable cause of this extinction, which can mainly be divided into events of a decline in the rate of diversification in the late Triassic contra a sudden and significant extinction event.

5. Lithofacies analysis and heterogeneity study of the subsurface Rhaetian-Pliensbachian sequence in SW Skåne and Denmark
University essay from Lunds universitet/Geologiska institutionenAbstract : The geological setting of Skåne is the outcome of successive phases of transtensional tectonics, block-faulting, subsidence, transpression and inversion focused around the Sorgenfrei-Tornquist Zone. The Höllviken Halfgraben is one of the major blocks in southwestern Skåne with a Rhaetian–Pliensbachian succession characterized by interbedding of arenaceous and argillaceous facies of local and regional extent.
