Irish Sea (including Kish Bank)

By D.I. Jackson, N.S. Jones and C.N. Waters


A thick and relatively complete succession of Carboniferous rocks of Tournaisian to\ud Westphalian age, together with a probable Stephanian section (Floodpage et al. 2001)\ud was deposited throughout the two main areas in the Irish Sea region. The larger Central\ud Province Trough in the south includes the East Irish Sea Basin (EISB)-Quadrant 109\ud Syncline-Kish Bank Basin, linking the onshore successions of the Craven Basin (Chapter\ud 11) and Dublin Basin (Chapter 21). The smaller Peel Basin-Solway Basin (Figure 16.1)\ud represents the extension of the onshore Solway Basin (Chapter 13) and continues\ud westwards between the Drogheda Shelf and the Balbriggan Block (Chadwick et al. 2001;\ud Sevastopulo & Wyse Jackson 2001). Seismic data suggest that there is probably some\ud 4000 m to 5000 m thickness of Carboniferous strata in the Solway Basin and EISB\ud (Chadwick et al. 2001). The present day distribution of Carboniferous strata is controlled\ud by the effects of uplift and erosion associated with Variscan basin inversion (Chadwick et\ud al. 2001). Separating the Solway Basin and EISB is the Manx-Lakeland Ridge, which is\ud believed to extend westward to form the Balbriggan Block (Chapter 18)
