... ensure rigour in how provenance data are interpreted. U–Pb geochronology of refractory zircon and relatively less stable apatite, and Pb isotopic analysis of labile K-feldspar are employed in this study to reassess the provenance of Triassic sandstones in the Slyne Basin, offshore western Ireland...

... achieved during the Late Jurassic. Continued local extensional reactivation of the listric detachment structure, post-Aptian, has resulted in a pattern of heterogeneous exhumation within the field area. However, the severely attenuated post-rift stratigraphic record throughout the Slyne Basin suggests...

... Abstract The Slyne Basin lies c. 60 km offshore west of Ireland, in water depths of 200–500 m. It consists of three asymmetric half-graben that are separated by complex structural transfer zones. Sporadic exploration in the basin over the last 20 years has resulted in the drilling of four...

... of this trend offshore Ireland (Slyne, Erris and Porcupine basins). Previously these organic-rich mudrocks were considered to be of little economic importance, due largely to their perceived limited areal distribution and low maturity. However, recent geochemical studies of oils and shales from exploration...

... in the Porcupine region were N–S throughout its Late Palaeozoic to Cenozoic history, while those in the Slyne, Erris, Rockall and probably Hatton basins were predominantly NNE–SSW to NE–SW. The main structural controls in the Goban region were orientated ENE–WSW and NNW–SSE. The Porcupine Basin is shown to have...

.... On the east flank of the Rockall Basin, the Benbecula gas and the Dooish condensate/gas discoveries have proven the existence of a petroleum system of unknown source – probably Upper Jurassic. The Corrib gas field in the Slyne Basin is evidence of a Carboniferous petroleum system. The three finds...

.... This observation is consistent with the presence of gas accumulations, which are postulated to have been derived from Carboniferous source rocks, in both the Slyne Basin and the Northwest Carboniferous Basin. Vitrinite reflectance (VR) is one method of evaluating the thermal alteration of sedimentary rocks...
