Relic-Soil on Limestone in South Wales
D. F. BALL
The Nature Conservancy, Headquarters for Wales and Bangor Research Station, Penrhos Road, Bangor, Caernarvonshire.
THE Worm's Head, part of the Nature Conservancy Gower Coast National Nature Reserve, lies at the south-western tip of the Gower Peninsula of Glamorganshire, South Wales. It is a Carboniferous limestone headland accessible only at low tide across a wave-cut limestone platform. On the southern side of the Inner Head (Ord. Surv. Grid Ref. SS 395873) is a section in Pleistocene deposits of a type recorded widely in Gower1–3, and elsewhere in southern Britain. This can be summarized from the base upwards as follows : (1) Wave-cut limestone platform; (2) raised beach of calcite-cemented limestone pebbles banked against solid limestone; the Patella beach; (3) remnants of bright red sandy clay loam, 10–18 in. thick, containing rare limestone pebbles with red weathered outer zones; (4) brown loam containing abundant angular limestone, a periglacial head deposit. The thickness of this is variable from 0 to 10 ft.; (5) dull grey-brown stony sandy loam, glacial drift containing abundant Old Red Sandstone and Carboniferous grits and sandstones; where this is preserved on the flanks of the Worm's Head, the depth averages 4–6 ft.; (6) dull, grey-brown, sandy loam, almost stoneless, similar to the matrix of horizon 5, resting variously on horizons 2, 3 or 6.
