Nolton Haven to Newgale
The small Nolton-Newgale coalfield is separated by faulting from the main Pembrokeshire coalfield. It lies mostly within Pennant Sandstone Formation of the Upper Coal Measures rocks.
Heading north along the coast path from Rickets Head, the site of Trefrane Cliff Colliery comes into view, with its spoil heaps and prominent furnace chimney. The colliery worked the Cliff Vein coal seam, pieces of which can be readily found in the spoil heaps.

The small Nolton-Newgale coalfield is separated by faulting from the main Pembrokeshire coalfield. It lies mostly within Pennant Sandstone Formation of the Upper Coal Measures rocks.
Heading north along the coast path from Rickets Head, the open expanse of Newgale Sands and the wide sweep of St Brides Bay dominates view. In this zoomed-in view over Newgale Sands, the pale coloured cliffs in the distance are Pre-Cambrian volcanics, with darker grey Cambrian sediments to the right (above the line of surf).

Heading north along the coast path from Rickets Head, the open expanse of Newgale Sands and the wide sweep of St Brides Bay dominates view. Ramsey Island is visible on the skyline on the extreme left; the summit of Carn Llidi just left of centre.
Seaward dipping beds of the Pennant Sandstone Formation form the wave-cut platform in the foreground.

This northward view from the coast path from Rickets Head shows Newgale Sands in the background. On the right of the photo, behind the fence is a spoil heap in the vicinity of the shaft of Black Cliff (Rickets Head) Colliery which worked the Black Cliff Vein.

Nolton Haven to Newgale
The small Nolton-Newgale coalfield is separated by faulting from the main Pembrokeshire coalfield. It lies mostly within Pennant Sandstone Formation of the Upper Coal Measures rocks.
This southward panoramic view from the coast path shows Rickets Head on the right and St Brides Bay in the background. The present-day profile of the headland is a result of former coal mining activity and the removal of overburden to access the Rickets Head Vein coal which cropped out at the base of the sandstone which comprises the up-standing pillar of rock.
The coast path climbs up from Rickets Head over the disturbed ground and spoil heaps visible in the foreground.
On the left of the photo in the flatter grassy area, are old shafts and degraded, grassed-over, spoil heaps of Rickets Head Colliery which worked the underlying Black Cliff Vein.
Stratigraphically, the rocks of Rickets Head are the highest (youngest) in the Carboniferous sequence of the Pembrokeshire coalfields.

This northward panoramic view from the coast path shows Rickets Head. The westerly, seaward, dip of the strata (approx 20°) is well seen.The present-day profile of the headland is a result of former coal mining activity; the rounded gap in the centre of the photo is at least partly due to the removal of overburden to access the Rickets Head Vein coal.

The small Nolton-Newgale coalfield is separated by faulting from the main Pembrokeshire coalfield. It lies mostly within Pennant Sandstone Formation of the Upper Coal Measures rocks.
The cliffs of Nolton Haven expose predominantly deltaic channel sandstones, often with highly erosive bases with coarse, rip-up, channel-lag deposits. The general dip is around 20° to the south-west.

The cliffs of Nolton Haven expose predominantly deltaic channel sandstones, often with highly erosive bases with coarse, rip-up, channel-lag deposits. The general dip is around 20° to the south-west.
This photo shows planar laminated sandstones with an erosive base resting on the underlying sandstone unit. Planar laminated sandstones in this setting often indicate high energy, fast current flow.
The photo is approx. 60 cm from top to bottom.
