Cambrian (Series 3 - furongian) conodonts from the alum shale formation at Slemmestad, Oslo region, Norway
(Peer reviewed; Journal article, 2018-05-09)Nine samples from the Alum Shale of Slemmestad, Oslo Region, were processed for conodonts. The limestone-rich interval extending from the mid Cambrian Paradoxides paradoxissimus trilobite Zone to the Lower Ordovician ... -
Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
(Peer reviewed; Journal article, 2018-11-20)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -
Facies, palynostratigraphy and sequence stratigraphy of the Wilhelmøya Subgroup (Upper Triassic–Middle Jurassic) in western central Spitsbergen, Svalbard
(Peer reviewed; Journal article, 2019)The Wilhelmøya Subgroup (Norian–Bathonian) is considered as the prime storage unit for locally produced CO2 in Longyearbyen on the Arctic archipelago of Svalbard. We here present new drillcore and outcrop data and refined ... -
Fluid flow properties of the Wilhelmøya Subgroup,a potential unconventional CO2 storage unit in central Spitsbergen
(Peer reviewed; Journal article, 2019)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
The timing of deglaciation and the sequence of pioneer vegetation at Ringsaker, eastern Norway – and an earthquake-triggered landslide
(Peer reviewed; Journal article, 2018)We describe a sediment sequence comprising a thick till covered by thin beds of lacustrine sediments containing pollen and plant macrofossils derived from pioneer vegetation. Four consistent radiocarbon dates on terrestrial ...
