  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. Strategies and Outcomes of Integrated Public Transport Planning : An Evaluation of Urban Development Strategies and Outcomes in the Tramway Line Extension from Ljura to Navestad in Norrköping

    University essay from Linköpings universitet/Institutionen för tema

    Author : Adrian Ibenholt; [2022]
    Keywords : Public transport; Tramway; Transit-Oriented development; Urban development; Evaluation; Theory-based evaluation;

    Abstract : Many researchers in planning have demonstrated the connection between land-use planning and transport planning. Mainly to describe how urban development can reduce emissions and congestion in cities. That public transport can be used as a tool in urban development is not as researched but is a general idea among planners and researchers. READ MORE

  4. 3. Ancient plant cuticle chemistry: preservation and characterization of organic matter as biomarker of past UV-B radiation

    Abstract : Biologiska processer hos olika organismer påverkas av ultraviolett-B-strålning (UV-B). Kunskapen om förändringar i UV-B-flödet som nått planetens yta under det geologiska tidsspann sedan flercelligt liv uppstod är dock begränsad. READ MORE

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

    University essay from Lunds universitet/Geologiska institutionen

    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

  6. 5. Sedimentary Factories and Ecosystem Change in the Triassic-Jurassic Boundary Interval : Insights from the Skåne Area (Southern Sweden)

    Abstract : 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.
