Description: This site consists of roadside cuttings and quarry exposures located on a hillside west of the River Neath
near to its mouth, between Port Talbot and Neath.
This site is of special scientific interest for its exposures of late Carboniferous rocks which afford the
best available sections through the Carboniferous Rhondda Beds, in a deltaic facies. They show
exceptionally well developed sedimentary structures, in particular large-scale channels, and also the
upward - fining cyclicity of the sedimentation, which is characteristic of such deltaic sediments. This
section is of outstanding interest for understanding the pattern of sedimentation in South Wales during
the late Westphalian, particularly how the environment changed following the uplift of the landmass to
the south of the coalfield during mid - Westphalian C times. A nationally important site for interpreting
Westphalian geological history.
