The geology of NY76NW (S) Cawfields, Northumberland

This field report provides a summary of geological information to accompany the recently resurveyed 1:10 000-scale sheet NY76NW (S), Cawfields, Northumberland. It should be consulted in conjunction with the published geological standard maps and fieldslips corresponding to this area. The area comprises Carboniferous sedimentary rocks of the Northumberland Trough, an asymmetrical basin and Carboniferous depocentre of the ‘block and basin’ structure of northern England. These strata dip by up to 15° towards the south and towards the southern margin of the Northumberland Trough. The early Permian Great Whin Sill is exposed at surface, thus forming a prominent ridge through the area. Superficial deposits originating from the late Devensian glaciation and subsequent Holocene processes intermittently blanket the bedrock.
