Nolton Haven sandstone channel edge 2

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.

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 erosive channel-lag deposits of sandstone blocks, ironstone pebbles and detatched coal lenses all cutting down at a steep angle into the underlying sediments.

The walking stick is 90 cm long.
