Yoredale Series

The Yoredale Series is a now-obsolete geology term for a local phase of Carboniferous rocks in northern 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. The name was introduced by J. Phillips on account of the typical development of the phase in Yoredale (now generally known as Wensleydale), Yorkshire.
