...I. P. TUNBRIDGE Abstract The Hangman Sandstone Group (Eifelian) of North Devon contains two continental 'Old Red Sandstone' formations. The Trentishoe Formation is some 1000 m thick and consists of lithic arenites which petrographically match closely with those in the higher parts of the Lower Old...

... the need for an ephermeral Bristol Channel Landmass to act as a sediment source. The possibility that the Welsh O.R.S. was some 400 km to the NW of the Trentishoe Formation during the Devonian is at variance with Dr Tunbridge s assertion that he has clearly demonstrated that the source of the Hangman...

The succeeding Trentishoe and Rawns formations are ephemeral low sinuosity stream deposits (Tunbridge 1980, 1981a) and the highest two (Sherrycombe and Little Hangman) are shallow marine. This paper analyses the shelf to foreshore...
