Description

Description Ty'n-y-Ffordd Quarry is notified for its geological interest more particularly for exposures of the Lower Elwy Group and Upper Nantglyn Flags of the Ludlow Series of the Silurian. The junction between the two marks a sharp change from well-bedded siltstones in the Nantglyn Flags below to slump bedding in the siltstones of the Elwy Group above. The contorted Strata of the latter have been attributed to turbidity flaws moving downslope. Such rocks are a characteristic feature of the Ludlow sediments of the Denbigh area.
