Analysis of Late Paleozoic-Mesozoic brittle faults and fractures in West-Finnmark: geometry, kinematics, fault rocks and the relationship to offshore structures on the Finnmark Platform in the SW Barents Sea
Lea, Halldis (Master thesis; Mastergradsoppgave, 2016-05-29)The present work focuses on the onshore/offshore analysis and correlation of brittle faults and fractures on the Porsanger Peninsula area in west-Finnmark, the shelf areas and the immidiate offshore areas (Finnmark Platform and Gjesvær low). Structural field observation, microstructural and SEM analysis provide the basis for the characterization of the geometry, kinematics and fault rocks. This data ... -
Late Devonian–Carboniferous faulting and controlling structures and fabrics in NW Finnmark
Koehl, Jean-Baptiste P.; Bergh, Steffen G; Osmundsen, Per Terje; Redfield, Thomas Fitzmaurice; Indrevær, Kjetil; Lea, Halldis; Bergø, Espen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-10)In the SW Barents Sea, Devonian–Carboniferous collapse led to the formation of major basins and faults, e.g., the Hammerfest Basin bounded by the Troms–Finnmark Fault Complex, and rhomboid- to sigma-shaped (half-)grabens on the Finnmark Platform. High-resolution aeromagnetic and bathymetry data from the shallow shelf show that analogue fault systems are present in coastal and onshore areas of NW ...
