Butley, Suffolk (TM 37155105)
The old pit at Neutral Farm lies just south of a small lane linking Butley and Butley Mills. Here ‘Butleyan’ Red Crag, at one of its most northerly exposures, was formerly seen to a thickness of over 6 m (Dixon, 2004). A lower thick unit, over 3 m thick, showed cross-bedded, medium- to coarse-grained shelly sands. Dip direction of the foresets indicates dominant sand transport to the south-west and deposition at 10-20 m water depth. Overlying this lower unit unconformably is 3.1 m of trough cross-bedded sands containing burrows and grading upwards into laminated silts and fine sands. Neutral Farm is unusual in being a rare locality containing both terrestrial and freshwater molluscs in the marine sediments of the Red Crag.
