Beyond the sands, where the ground rises, a band of consolidated 
gravel, with a few shells, chiefly patella, occurs on the face of the cliff, 
the northern point of the bay ; the clay, with striated boulders and local 
débris, resting upon metamorphosed schists. 
Boulder Clays of the North-East. 
Under this name are comprised a series of gravels, fine clays, and 
elays replete with rocks and boulders exhibiting signs of glacial action. 
The majority of these, unlike those in the limestone drifts further south, 
are much rolled and water-worn. In a section now obscured by talus, 
on the coast road from Larne to Glenarm, near Ballyrudder, the lowest 
beds consist of current bedded shelly gravels, yielding a fauna containing 
a percentage of nearly 35 per cent. of exotic forms, a larger percentage 
than occurs in any other Ivish post-tertiary deposit. Mr. Stewart records 
(‘Proc, Belfast Nat. Field Club,’ Appendix, 1879-80) the following species. 
The exotic forms are distinguished by the mark *; those on Canon

esse CALCaTes: 
These gravels are succeeded by sands and clean clays, or with seams 
of fine gravel, passing upwards into a clay containing much chalk, and 
lastly into a very stiff, unfossiliferous, unstratified clay, full of rocks and 
glaciated stones.
