Pembrokeshire

Pembrokeshire Coast Path from St Govans to the Green Bridge of Wales At Bullslaughter Bay, the Dinantian age Carboniferous Limestone Series has been eroded along folds and fractures into a series of sea caves and sea stacks. The main structure is the Bullslaughter Bay syncline, the axis of which runs from near the caves on the left of the photo and crosses the sandy beach. Some of the fractures are filled with orange-brown, angular brecciated sediment ('Collapse Breccia'), thought to be of Triassic age.

The main structure is the Bullslaughter Bay syncline, the north-dipping limb of which is visible to the right of the centre.

Pembrokeshire Coast Path from St Govans to the Green Bridge of Wales Just west of Bullslaughter Bay, the Dinantian age Carboniferous Limestone Series has been eroded along a series of angular folds and fractures, forming a set of sea caves and sea stacks.

Pembrokeshire Coast Path from St Govans to the Green Bridge of Wales A westerly view of the cliffs of Dinantian age Carboniferous Limestone Series, viewed from Mewsford Point on the south Pembrokeshire coast. In the centre of the photo is a series of angular folds, associated with the Bullslaughter Bay syncline (just out of sight behind the nearest cliff headland). The flat landform topography represents the '200 foot platform' - a Tertiary age marine erosion surface.

St Govan's Head is just to the right of centre. The rocks dip gently to seaward (south). The flat landform topography represents the '200 foot platform' - a Tertiary age marine erosion surface.

Coastal traverse and geology from Waterwynch to Saundersfoot, Pembrokeshire The fields and hedgerows looking inland, south west, from the coastal path above Brownslade Bay just north of Waterwynch. I loved the quality of the afternoon light on the hedgerows.

Coastal traverse and geology from Waterwynch to Saundersfoot, Pembrokeshire At Monkstone Point, grey, channel-fill sandstones of the Namurian age 'Millstone Grit Series' have been folded into a complex anticline with subsidiary folds, thrusts, and bedding plane slips which accommodate the 'space problem' in the core of the main anticline. These sandstones are probably the equivalent of the prominent overturned sandstone ribs at Trevayne Point at the south end of Monkstone Bay.

Coastal traverse and geology from Waterwynch to Saundersfoot, Pembrokeshire The high cliff of Trevayne Point is just to the north of Lodge Valley beach. The rocks here are mostly pale grey sandstones of the Namurian age 'Millstone Grit Series' which have been folded into a nearly concentric anticline (on the left side of the cliff), with a near vertical, slightly overturned northern limb visible in the centre and right-hand side of the photo.
