Abstract
I. I ntroduction . T he exact stratigraphical position of the Blea Wyke Beds and their relations to the beds above and below them have given rise to a great deal of discussion, but no very satisfactory conclusion seems to have been reached by any of the writers on the question. Many attempts have been made to assign these beds to the Lias or to the Inferior Oolite, but hitherto there has always been some objection to drawing a hard-and-fast line at any particular horizon; and in these days, when less importance is attached to arbitrary divisions of geological time, and more to broad questions of physical geography, it seems worth while to study the question afresh from a more modern standpoint. These beds are also noteworthy for another reason, because a study of them seems to throw some light on the history of the Peak Fault, perhaps the greatest and most important dislocation in North-East Yorkshire. Before beginning the detailed study of the Blea Wyke Beds, it will be necessary to say a few words concerning the general structure of the district in which they are developed. The southernmost exposure of the Lias on the Yorkshire coast is in the cliffs below what was formerly known as Peak, but now called Ravenscar. At this point the beds have a rather steep dip to the south, and by proceeding northwards from Staintondale, we pass in succession over a fine series of Oolitic and Liassic strata. The Oolites form the cliffs as far north
