MIDDLE CHALK—KENT. 
381 
At Charing the large quarry north of the village shows 50 feet 
of firm white, massivety-bedded chalk belonging to the lower part 
of the same zone ; at the base of the quarry face is a marked nodule- 
bed which contained many lumps of iron pyrites ; spines of Cidaris 
serrifera also occurred in it. Rhynchonella Cuvieri (small), Tere- 
bratula semiglobosa, and Lima spinosa were obtained throughout, 
but only two or three specimens of Terebratulina gracilis var. lata 
were found, and those in the upper part of the quarry. A few flints 
were seen at the top. 
The Hart’s Hill quarry, a little further west, is in chalk at a some¬ 
what lower horizon, and probably touches the zone of Rhyne. Cuvieri. 
In the lower part of the quarry Calerites subrotundus occurred ; 
in the higher part there is a face of some 55 to 60 feet in white, 
softish, blocky chalk, a marl band and a few flints occurring 
quite at the summit. 
A typical example of these practically disused quarries is that at 
Lenham Hill; the whole section was accessible in 1896, and was

The base of the Middle Chalk and its junction with the Belemnite 
marls is exposed in an excavation made for rifle butts, three-quarters

The Melbourn Rock is again exposed near Cobham Farm (see 
p. 48), and in the lane leading to Boarley. 
A fine section through the greater part of the Terebratulina 
zone is to be seen in the large quarry at Hollingbourne Hill, which
