IV.—On a New Marine Bed in the Lower Oolites of East Yorkshire

Abstract

About half-way between Hayburn Wyke and Cloughton Wyke, and five miles North of Scarborough, a scar of hard sandstone, remarkable for its even bedding, may be seen rising with a considerable dip from the sea. This sandstone contains along its bedding planes occasional thin layers of a very dense ironstone, from which it has probably received the name of ”Iron Scar.“ Immediately beneath are about five feet of shales closely resembling those of the Middle Lias, and containing two bands of dogger ironstone.
