Nolton Haven ironstone pebbles in channel lag deposits

Nolton Haven ironstone pebbles in channel lag deposits
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 a close-up view the erosive channel-lag deposits with a prominent layer (approx. 30 cm thick) of ironstone pebbles.
