1. The Origins and Ecology of Early Paleozoic Spreiten Ichnofossils: Comparisons of Daedalus and Syringomorpha with Alectorurus
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Cambrian explosion not only shaped the ecosystems of the Phanerozoic, but fundamentally changed how biota interacts with the environment, including the substrate. Cambrian trace fossils Alectorurus and Syringomorpha as well as Ordovician-Silurian Daedalus represent novel modes of faunal interaction with the newly innovated shallow marine mixed-ground and have surprisingly limited stratigraphic ranges.

2. 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.

3. First-arrival traveltime tomography of active-source data in the Kansanshi copper mine, northern Zambia
University essay from Uppsala universitet/GeofysikAbstract : Sedimentary rock-hosted deposits are a major source of copper and cobalt, with the Neoproterozoic central African Copperbelt being among the largest Cu-Co provinces in the world, accounting for around 15% of its copper resource. The deposits occur primarily in the carbonates and siliciclastic sediments overlying the basement, and formed during early diagenesis (around 820 Ma) and late diagenesis/metamorphism during the Pan-African Orogeny (580-520 Ma).

5. Modelling of the Normal Fault Pattern above a Basement Horst in the Lufeng Sag, China
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The analogue models and the kinematic models based on the seismic data results were used to simulate the fault pattern which develops above a basement horst. The two major normal faults intersect with each other along the strike in the sedimentary covers. READ MORE
