This paper discusses the development of the Faeroe-Shetland Basin. The area has been affected by at least five rift events from the Permo-Triassic to the Paleocene. Numerous authors have invoked the reactivation of older structures as a major influence on subsequent tectonic events. In this paper the aim is to demonstrate that the locus of rifting shifted with time.
A consistent stratigraphic study of the western European Carboniferous Basin has allowed the generation of eight palaeogeographic timeslices. These illustrate a model of large scale eastern (dextral) tectonic escape on the northern side of a convergent margin and integrate the diverse tectonic and sedimentary settings observed within the basin as a whole. This model can be compared to the present day eastern Mediterranean, where a similar range of diverse tectonic settings are observed. Reservoir and source distribution is discussed for each time-slice along with the present distribution of Carboniferous oil and gas fields. Due to the diversity observed no unique play type can be distilled from the data to explain the distribution of hydrocarbons within the studied area.
The magnetostratigraphy of two cores from the late Triassic Lunde Formation of the northern North Sea are compatible with the calibrated magnetostratigraphy for the Norian stage determined by Gallet et al. (1993) from Tethyan carbonates. The polarities of the cores indicate a lower to upper Norian age for core 9/13A-36 and lower to middle Norian age for core 9/13A-A45. The isolated characteristic magnetizations are due to a Triassic detrital remanent magnetization, which is partially overprinted with a drilling-induced remanence of two origins. The drilling-induced remanences are associated with (1) the main coring procedure, producing an overprint which is oriented downcore and (2) the subsample coring procedure, which produces an overprint parallel to the subsample core axis and directed outwards from the main core axis. The elimination of those specimens with a significant drilling-induced remanence is important for the determination of the magnetostratigraphy in these cores.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
