Extract

The Hangman Grits of the Quantocks consist of a series of sand-stones, now, in most instances, practically converted into quartzites by the great pressure to which they were subjected during the Armorican movements, and occasional shales, which sometimes show cleavage. There are also beds, never of any great thickness, which bear a strong resemblance to the Keuper Marls. Fossils, other than a few obscure plant-remains, are unknown, except in the beds which are usually regarded as forming the top of the series, where marine fossils occur as casts in what is evidently a decalcified calcareous sandstone.
