Stratigraphy

| Stratigraphy comments: "Traditionally, the rocks exposed on Hilbre have been assigned, as part of the Cheshire Basin, to the Chester Pebble Bed Formation (formerly Bunter Pebble Beds) of the Lower Triassic. Evaluation of the footprint assemblage and the sedimentology of the beds tests and generally supports the recent hypothesis of the British Geological Survey that the exposures on Hilbre should be reassigned to the Ormskirk Sandstone Formation (Middle Triassic) within the East Deemster sub-basin (part of the East Irish Sea Basin)... [from the] Lower Anisian (Middle Triassic)." (King & Thompson, 2000) |
