A feature of the geology of England, the Stafford Basin extends beneath much of the Midlands county of Staffordshire.
The sedimentary sequence, principally sandstones and mudstones, within the basin is continuous with that of the adjoining basins in the rift complex.
Deposition of the Chester Formation (formerly Chester Pebble Beds) for example is ascribed to a river flowing north from the Worcester Basin through the Stafford Basin and on into the Cheshire and East Irish Sea basins during the early Triassic.
In contrast the Bridgnorth Sandstone Formation of this area is of aeolian origin, the equivalent of the Collyhurst Sandstone of the Cheshire Basin.
