Pembrokeshire Coalfield

Map of British Coalfields

The Pembrokeshire Coalfield in West Wales is one of the smallest British coalfields. The main coalfield extends from Saundersfoot on Carmarthen Bay westwards to Broad Haven on St Brides Bay. A small detached portion of the field is centred on Newgale on St Brides Bay.[1]

The coalfield is in effect the westernmost extension of the South Wales Coalfield though it is separated from the main body of that field by Carmarthen.

Coal seams within the Pembrokeshire Coalfield are traditionally referred to as veins. The following sequence is recognised in the west of the district:[2]

  • Rickets Head Vein
  • Black Cliff Vein
  • Cliff Vein
  • Hookes Vein
  • Folly Vein
  • Folkeston Vein
  • Haggard Vein
  • Stonepit Vein
  • Quarry Vein
  • Yard Vein
  • Stink Vein
  • Five Feet Vein
  • Three Quarter Vein
  • Brawdy Veins

The Stonepit and Quarry Veins are collectively referred to as the Sibbernock Veins. The sequence from the Three Quarter to the Foot Vein constitutes the Newgale, Simpson and Eweston Coals.

In contrast in the centre and east of the district, there are fewer veins in what is a more compressed sequence:
