XV. Remarks on the Position of the Upper Marine Formation 

 exhibited in the Cliffs on the North-east Coast of Norfolk. 

 By Mr. Richard Taylor of Norwich. 



To the Editors of the Philosophical Magazine and Journal. 



T^HE accompanying sketch (Plate I.) represents the section 

 -*- of about a quarter of a mile of the cliff' immediately to the 

 west of Cromer Jetty, at a point which attracts the notice of 

 the geological observer to the singular contortions of the di- 

 luvial beds ; and is further remarkable by the singular posi- 

 tion and expansion of the crag strata. 



In pursuing the line of cliff's from their commencement at 

 Weyburn Hope, a thin bed of ferruginous gravel and cjay 

 may be traced, almost uninterruptedly, along the coast, for 

 about seven miles, to this spot. This bed seldom exceeds two 

 feet in thickness, and for the most part is visible immediately 

 overlying the upper chalk series, which rises to the surface 

 about three miles west of Cromer. An apparent continuation 

 of the same bed may be traced from hence southward, about 

 fifteen miles; appearing in general, just above the high -water 

 mark, sometimes laminated and often contorted or waving, 

 and varying at every hundred yards its component qualities, 

 through every modification and combination of ferruginous and 

 ochreous sand, gravel, clay, peat * and loam, with more or less 

 of compressed wood ; stumps of trees rooted into the stratum ; 

 ochreous nodules and nuclei ; shelly and bony fragments ; 

 teeth, tusks and horns of elephants and deer; in all which 

 properties it preserves a certain general and remarkable cha- 

 racter by which it can be identified throughout an exten- 

 sive line of the eastern coast, occupying the position usually 

 assigned to the crag or upper marine formation, and which 

 I have previously noticed in the article in volume lx., August 

 1822. 



* In one of these peat beds I observed a numerous colony of recent 

 and living pholades.
