The Riccarton Group is a Silurian lithostratigraphic group (a sequence of rock strata) in southern Scotland and northern England. The name is derived from Riccarton in the Edinburgh area. The rocks of the Riccarton Group have also previously been known as the Riccarton Formation and the Riccarton and Raeberry Castle Beds.[1] The Group comprises around 500m thickness of greywackes, mudstones and siltstones which are faulted and folded.
