Description

Details

This desert sandstone is from the Triassic. Approximately 200 Ma. It belongs to the group of rocks known as the New Red Sandstone which date from the Permian (280 Ma) into the Triassic. The sandstones are composed solely of speroidal (millet seed) quartz grains with an iron oxide cement, haematite. This lithology is typical of an aeolian hot desert environment. Rare interbedded evaporite deposits of Halite & Gypsum are occasionally seen. This example is from Lazonby, near Penrith, Cumbria. These specimens are supplied in labelled card trays.
