Lower chalk—Kent. 
47 
4 to 5 feet of greyish-white marly chalk is exposed, containing 
(.Ammonites varians, and Am. Goupei), and beneath it is soft 
buff-grey marl. Following the stream downwards, the glauconitic 
sandy marl is found with a thickness of 5 feet at least; its junction 
with the chalk is not seen, nor is that with the Gault easily traced, 
but the impression conveyed by a succession of specimens brought 
up by a hand-augur was that the glauconitic bed passed gradually 
to the Gault without a well-marked base line. 
Chalk Marl— There do not appear to be many quarries in 
this part of the Lower Chalk in Kent. Portions of it are shown 
occasionally in road cuttings, but we have not been able to examine 
the course of outcrop in sufficient detail to trace the minor beds of 
the coast section inland. 
Two or three miles east of Wye hard beds occur low down in the 
Chalk Marl, apparently rather nearer the base than at Folkestone, 
but this may be partly due to the thinning of the Stauronema zone. 
They are seen in the lane leading from the main road to Bull Town 
Farm, and they yielded Am. [Schloenbachia] varians , Scaphites. 
tcqnalis, Terebratula biplicata , Pecten orbicularis, and Plicatula 
inflata. 
Shallow cuttings at Giddy Horn Wood, Cocklescombe, and New¬ 
gate Scrubs show the same beds. 
The best inland section is probably that in the cutting which 
leads from the brickyard at Bur ham to the large quarry half a mile 
east of Burham. The basement bed is seen at the entrance 
of the cutting, and further on beyond the tunnel the following 
section was taken by Mr. W. Hill in 1896 : —

The sides of the cutting are very steep, so that the upper part was 
inaccessible, but portions weathered out as if harder than the rest. 
In a quarry about 200 yards south of the Black Horse Inn at 
Thornham 20 feet of the Lower Chalk is seen, very much broken 
up, as usual. {. 
Zone of Holaster subglobosus. 
Numerous small quarries along the base of the North Downs 
east of Wye show the highest part of the Lower Chalk.
