Gospel End Road Cutting: SO 904936
This is the best available exposure of so-called 'breccias' belonging to the Etruria Formation. They are of considerable interest because they represent sediments formed during the transition to desert conditions in the Late Carboniferous to Early Permian, reflecting world-wide climatic changes occurring at this time. The sequence actually represents mainly fluvial channel deposits with pebbly lags, with minor overbank deposits, and is the most typical development of this formation.
