GEOLOGICAL SURVEY 



OF THE YORKSHIRE COAST. 



PART 1. 



DESCRIPTION OF THE STRATA. 



JL HE whole of the rocks of this district, with the exception of a 

 basaltic dyke that intersects a part of them, belong to the family of 

 Jtat rocks. They lie in what is called a conformable series, that is, 

 a series observing a kind of parallelism. Their general dip is towards 

 the south, but at a great variety of angles, -and with not a few contor- 

 tions and irregularities ; the strata frequently bending or undulating, 

 in a curved form, and exhibiting in some places considerable breaks 

 vr dislocations. 



In studying the characters and positions of these strata, at least 

 where they form a part of the western barrier of the German Ocean, 

 we have this important advantage, that they are all accessible, and 

 open to inspection. Here the section of the strata is not, like 

 the generality of sections, partly taken from observation, and partly 

 filled up by fancy or conjecture: the whole is a real section, fcopied 

 from nature ; the steep sea-cliffs disclosing the whole series of beds in 

 their proper order, together with their contortions and irregularities.
