A string of workings on lenticular deposits of anthracite, and the associated paint pigment deposits, found in the Culm Measures between Abbotsham on the coast and Hawkridge Wood on the River Taw south-east of Tawstock.
The most extemsive workings are in the Bideford area - the Union Mine under the western part of the town; the Bideford Anthracite Mine, at East the Water, and the Bideford Black Mine, in the Chapel Park area. Other workings include the Tawstock Mine, at Somers Hiscott, and the Hawkridge Culm Works, on the east bank of the Taw.
