Lateral compositional variations in the Upper Jurassic source rock in the southwestern Barents Sea – an organic or inorganic disclosure
Helleren, Solveig (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Prominent high-value gamma-ray spikes in the maximum flooding surfaces of the Alge Member of the Hekkingen Formation display an uncommon stratigraphic and regional variation in the southwestern Barents Sea. The variation ... -
The Middle Jurassic to lowermost Cretaceous in the SW Barents Sea: Interplay between tectonics, coarse-grained sediment supply and organic matter preservation
Marin Restrepo, Dora Luz; Helleren, Solveig; Escalona Varela, Alejandro; Olaussen, Snorre; Cedeno Motta, Andres Felipe; Nøhr-Hansen, Henrik; Ohm, Sverre Ekrene (Peer reviewed; Journal article, 2020)Syn‐rift successions contain both prolific organic‐rich and coarse‐grained rocks, but these rocks are usually studied independently. Thus, the interplay among organic matter deposition, tectonics and sediment supply is not ...
