Greywacke forming at the edge of Gondwana

Greywacke forming at the edge of Gondwana

This diagram is a reconstruction of how Torlesse greywacke and associated sediments formed at the edge of the Gondwana supercontinent. Rivers carried sediment from land out to sea on the continental shelf, where it was then transported down channels as turbidity currents onto huge submarine fans on the deep ocean floor.
