Red sandstone

(Geol.) See under Sandstone.
a name given to two extensive series of British rocks in which red sandstones predominate, one below, and the other above, the coal measures. These were formerly known as the Old and the New Red Sandstone respectively, and the former name is still retained for the group preceding the Coal and referred to the Devonian age, but the term New Red Sandstone is now little used, some of the strata being regarded as Permian and the remained as Triassic. See the Chart of Geology.
