Gedgrave, Suffolk (TM 40534859)
Two pits currently exist at Gedgrave Hall. The larger, more northerly pit is degraded and shows only 2.3m of Coralline Crag in an exposure about 10m wide. The cross-bedded sands of the Sudbourne Member have a maximum set thickness of about 1m. Foresets dip steeply towards SSW, similar to dip directions observed at other localities. Most of the aragonitic material has been leached, leaving highly comminuted and abraded calcitic shell material. A second pit, a few metres to the south and slightly downslope, is a small exposure of about 40cm of unleached Crag with poorly-defined cross-bedding. This is probably also Sudbourne Member but very close to the contact with the underlying Ramsholt Member.
Gedgrave Hall is one of the most southerly exposures in the Sudbourne Member and skeletal material derived from the north has therefore suffered longer transportation and abrasion than at other localities. The lack of identifiable macrofauna is thus thought to be mainly due to the effects of prolonged transportation.
