The Patos-Pernambuco shear system of NE Brazil: Partitioned intracontinental transcurrent deformation revealed by enhanced aeromagnetic data
(Journal article; Peer reviewed, 2022)The Neoproterozoic-Cambrian (Brasiliano) intracontinental Patos-Pernambuco shear system is developed in Archean to Neoproterozoic crust, reactivating rift margins N of the São Francisco Craton. We here use enhanced ... -
Permian-Triassic tectonic-stratigraphic evolution of the Stord Basin, northern North Sea
(Master thesis, 2016-08-19)The Stord Basin is one of the less explored areas of the northern North Sea, hence the Permian- Triassic tectono-stratigraphic evolution of the basin is not well known. This MSc thesis aims to use available 2D seismic and ... -
Persistence of arctic-alpine flora during 24,000 years of environmental change in the Polar Urals
(Peer reviewed; Journal article, 2019-12-23)Plants adapted to extreme conditions can be at high risk from climate change; arctic-alpine plants, in particular, could “run out of space” as they are out-competed by expansion of woody vegetation. Mountain regions could ... -
Pervasive cold ice within a temperate glacier – implications for glacier thermal regimes, sediment transport and foreland geomorphology.
(Peer reviewed; Journal article, 2019-03-07)This study suggests that cold-ice processes may be more widespread than previously assumed, even within temperate glacial systems. We present the first systematic mapping of cold ice at the snout of the temperate glacier ... -
Petrogenesis of zoned and unzoned mafic pegmatites: An insight from the Palaeoproterozoic mafic-ultramafic Hamn intrusion, Northern Norway
(Journal article; Peer reviewed, 2022)Mafic pegmatites have been reported from various geological environments, including ophiolites, layered magmatic intrusions, and volcanic arcs, but their petrogenesis stayed poorly constrained. This study brings new ... -
Petrography and U-Pb SHRIMP zircon geochronology of basement samples from a key area in central Dronning Maud Land, East Antarctica: Implications for the eastern extension of the Grenville-age Maud Belt in Antarctica
(Master thesis, 2017-06-15)Central Dronning Maud Land, East Antarctica represents a key area for the understanding of previous supercontinent assemblies. This study reports U/Pb SHRIMP ages and petrographic descriptions for nine samples collected ... -
Petrography, geochemistry and sedimentology of sandstones from the Central Tertiary Basin of Svalbard – implications for diagenesis and temperature history
(Master thesis, 2019-10-03)Svalbard, representing an uplifted area of the north-western Barents Sea Shelf, provides a unique opportunity for studying on-shore outcrops of the shelf. The present study focuses on Paleocene-Eocene deposits of the Central ... -

Petroleum, coal and research drilling onshore Svalbard: a historical perspective
(Peer reviewed; Journal article, 2019)The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, ... -
Petrology and Provenance of the Upper Cretaceous Strata in Central Utah
(Master thesis, 2015-06-01)The reservoir quality of sandstones is primarily controlled by the primary composition of the rock volume and the effects of later diagenetic processes. Much work has been done to improve the understanding of diagenetic ... -
Petrophysical properties of deformation bands and their influence on fluid flow in carbonate grainstones: insights from the Maghlaq Fault, Malta.
(Master thesis, 2015-06-08)Deformation bands are tabular, sub- centimeter thick zones, which accommodates shear and/or volumetric deformation. Only a few examples of deformation bands have been documented in porous carbonate rocks, and the knowledge ... -
Petrophysical Properties of Deformed Sandstone Reservoir
(Master thesis, 2012-06-21)Small scale deformation structures that mostly occur in highly porous rocks are called deformation bands. Petrophysical characteristics of deformation bands are different from those of host rock and they can act as barriers ... -

Physical modelling of the interplay between salt-detached gravity gliding and spreading across complex rift topography, Santos Basin, offshore Brazil
(Journal article; Peer reviewed, 2022)The Santos Basin, offshore Brazil contains a complex set of salt-tectonic structures, the origins of which are debated, that is, the Albian Gap and the São Paulo Plateau (SPP). The Albian Gap is a ca. 450 km long, 60 km ... -
Plaster modelling of fault development and geometry in contractional settings
(Master thesis, 2015-06-01)The aim of this study has been to analyse the development of contractional structures using analogue plaster models. Structures similar to natural fault systems are generated using plaster of Paris as the deforming medium ... -
Plaster modelling of fault development in extensional regimes
(Master thesis, 2015-05-31)The full complexity of deformation in natural extensional regimes is complicated, as direct observation in nature is limited in regards to outcrops and structural evolution over time. The aim of this thesis is to analyse ... -
Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean
(Peer reviewed; Journal article, 2003-01-10)We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sites (>3700 m) exhibit large ... -
Pliocene sea ice evolution in the Iceland and Labrador Sea – A biomarker approach
(Doctoral thesis, 2017-12-07)Sea ice plays a crucial role in the climate system. Although this is broadly acknowledged, the role of sea ice is not fully understood, especially during warmer periods such as the Pliocene (5.88–2.58 Million years ... -
Plume–MOR decoupling and the timing of India–Eurasia collision
(Journal article; Peer reviewed, 2022)The debatable timing of India–Eurasia collision is based on geologic, stratigraphic, kinematic, and tectonic evidence. However, the collision event disturbed persistent processes, and the timing of disturbance in such ... -
The PMIP4 contribution to CMIP6 – Part 4: Scientific objectives and experimental design of the PMIP4-CMIP6 Last Glacial Maximum experiments and PMIP4 sensitivity experiments
(Peer reviewed; Journal article, 2017)The Last Glacial Maximum (LGM, 21 000 years ago) is one of the suite of paleoclimate simulations included in the current phase of the Coupled Model Intercomparison Project (CMIP6). It is an interval when insolation was ...
