The sedimentary basins of Britain and Ireland are numerous, occurring beneath both the land surface of these islands and the surrounding seas. Sedimentary basins (not to be confused with drainage basins) have operated in this region over much of geological time from the Precambrian to the present day, typically accepting sediment from neighbouring areas where erosion is taking place, over timescales variously from millions to hundreds of millions of years. They may be referred to simply as basins or else as troughs, grabens or half-grabens, according to their mode of formation and morphology.
Key to table
edit- Column 1 indicates the name of the basin. Some variant names are recorded between sources. Sub-basins are noted.
- Column 2 indicates the area (country/sea) in which the basin occurs. Some extend across more than one. Sea areas include the Atlantic Ocean, North Sea, English Channel, Sea of the Hebrides, Irish Sea, Celtic Sea, Bristol Channel, The Minch
- Column 3 indicates the period(s) or epoch(s) during which it was active as a sediment sink. May not be exhaustive.
- Column 4 provides any additional notes
- Column 5 indicates a selection of publications in which references to the basin may be found. See references section for full details of publication.
