The picture shows a similar environment of deposition, in a desert in present day Central Asia.

During Permian and Triassic times the continents of the world were grouped together in the supercontinent Pangaea. There were
desert conditions across the Midlands and far beyond to the east right across Europe.

Mountains were eroded by catastrophic events producing the coarse angular deposits of the Haffield Breccia. Later in time sandstones and mudstones were laid down. In places there are ancient sand dunes and also salt lake deposits.
