The Yoredale Series, in geology, is a now obsolete term for a local phase of the Carboniferous rocks of the north of England, ranging in age from the Asbian Substage to the Yeadonian Substage. The term Yoredale Group is nowadays applied to the same broad suite of rocks.^[1] The name was introduced by J. Phillips on account of the typical development of the phase in Yoredale (now generally known as Wensleydale), Yorkshire.^[2]
