“…Evidence for rifting in the Carboniferous and the Early Triassic comes from East Greenland to the west (Stemmerik et al 1993;Surlyk 1990;Seidler et al 2004), with mid-Jurassic events recognized both in East Greenland (Price and Whitham 1997) and the Halten Terrace area (Corfield et al 2001). Intense Late Jurassic-Early Cretaceous rifting is well documented across the rift in East Greenland (Surlyk 1990) and Mid Norway (Swiecicki et al 1998;Doré et al 1999), leading to the formation of the Vøring and Møre basins (Brekke et al 1999), both of which contain very thick Cretaceous successions. A subsequent Late Cretaceous (Turonian) rift event affected the Vøring Basin, but apparently not the Møre Basin (Brekke et al 1999).…”

This paper explores the potential for use of rutile geochemistry as a provenance tracer in Jurassic-Paleocene sandstones in hydrocarbon exploration wells from the Norwegian Sea.Previous studies in this area, concentrating on provenance-sensitive heavy-mineral ratios, The development of rutile geochemistry as a provenance tracer is especially important given the stability of rutile in both diagenetic and surficial weathering conditions. The technique yields information that can be utilised to reveal the ultimate source-rock lithology and metamorphic facies, even in highly modified sandstones that may have lost most other provenance information.

“…The Norwegian continental margin records several pre-breakup rifting phases that played a major role in initiating the formation of deep sedimentary basins (Skogseid, 1994;Blystad et al, 1995;Swiecicki et al, 1998;Doré et al, 1999Doré et al, , 2002Brekke, 2000;5 Skogseid et al, 2000). For instance, the deep Vøring and Møre basins in the Norwegian Sea were formed due to the early rifting around 150 Ma ago and contain more than 10 kilometers of late Mesozoic deposits (Scheck-Wenderoth et al, 2007).…”

Abstract. The aim of this study is to investigate the shallow thermal field differences for two differently aged passive continental margins by analyzing regional variations in geothermal gradient and exploring the controlling factors for these variations.Hence, we analyzed two previously published 3D conductive and lithospheric-scale thermal models of the Southwest African and the Norwegian passive margins. These 3D models differentiate various sedimentary, crustal and mantle units and integrate different geophysical data such as seismic observations and the gravity field. We extracted the temperature-depth distributions 5 in 1 km intervals down to 6 km below the upper thermal boundary condition. The geothermal gradient was then calculated for these intervals between the upper thermal boundary condition and the respective depth levels (1, 2, 3, 4, 5, and 6 km below the upper thermal boundary condition). According to our results, the geothermal gradient decreases with increasing depth and shows varying lateral trends and values for these two different margins. We compare the 3D geological structural models and the geothermal gradient variations for both thermal models and show how radiogenic heat production, sediment insulating 10 effect, and thermal LAB depth influence the shallow thermal field pattern. The results indicate an ongoing process of oceanic mantle cooling at the young Norwegian margin compared with the old SW African passive margin that seems to be thermally equilibrated at the present-day.
