Abstract
The sedimentary succession on the remote Digermulen Peninsula at the western side of Tanafjorden belongs to the Gaissa Nappe Complex (Lower Allochthon) of the Caledonides of Finnmark. It comprises one of the most complete Ediacaran–Cambrian transitions worldwide and has attracted renewed research interest because of new findings of Ediacaran-aged fossils. During the last years, field and laboratory work by the Digermulen Early Life Research Group funded by the Norwegian Research Council allowed many discoveries regarding the fossil record and sedimentary rocks themselves. The new data allow for the first time a detailed analysis of sediment supply and to test current palaeotectonic models based on a multi‐method provenance approach on Ediacaran and Cambrian sedimentary rocks of the Digermulen Peninsula. In this talk, I will present and discuss some of the research highlights to decipher the sediment sources and track changes in the depositional environment through this important interval of Earth’s history.
