MIDDLE ALBIAN STRATIGRAPHY 



details of this section were recorded. Bisson in Smart et al. (1966 ; 100) has described 

 the Folkestone Brickworks section at Cheriton (TR 205376) in which I suspect that 

 the lowest 2 feet 6 inches (0762 m.) recorded as 'Dark-grey slightly micaceous 

 blocky clay with occasional phosphatic nodules ', underlying the basal cristatum 

 nodule bed, is of daviesi Subzone age as at Copt Point, and at Wye near Ashford. 

 However, I did not see this part of the succession. 



At Sandling Junction (text-fig. 4) the fauna of Bed 9 classified with the spathi 

 Subzone is identical to that of Division A in the Maidstone By-Pass (Owen i960 ; 

 372), and so, the age of the dentatus nodule bed has already changed at the outcrop 

 within 5 miles (8-05 km.) of Copt Point (Owen 1963a; 49-50). No fossils have yet 

 been found in the underlying glauconitic loams of Beds 4-8. Bed 8 (of Worssam 

 1966 ; 99) at File's pit in Swan Lane, Sellindge (TR 11853915) is the equivalent of 

 Bed 9 at Sandling, and Bed 6 yielded the specimen of Hoplites ? recorded by Worssam.

Fig. 4. Section in Gault-Lower Greensand junction beds at Folkestone Quarries Ltd's 

 Sandling Sandpit, c. 150 yds. NW. of Sandling Junction railway station, Saltwood, Kent 

 (TR 14703690). 



This specimen (GSM., CW 855) is a definite Hoplites (H.) but there is no other 

 indication of the age of the sediments overlying the puzosianus Subzone sediments. 

 The principle bed of phosphatic nodules in the spathi Subzone sediments at the 

 Granary Court Sand pit at Brabourne (TR 09004005) is also on the same horizon as 

 that of Bed 9 at Sandling. At Brabourne, in the area where Hill (in Jukes-Browne 

 1900 ; 84) records a section, the former Ashford & Naccolt Brick, Tile & Potteries 

 Ltd., dug shallow pits in higher beds of the Lower Gault about 800 yards (731 m.) a 

 little north of west from Park Farm (TR 08904065). About 8 feet (2-43 m.) of 

 weathered brownish clay streaked with ferruginous matter was to be seen beneath 

 superficial deposits. Towards the top of the clays a disturbed seam containing 

 phosphatic nodules yielded fragments of the following : — 



Anahoplites planus (Mantell), A. pleurophorus Spath, Dimorphoplites aff. niobe, 

 D. cf. doris Spath, Enhoplites cf. subtuberculatus Spath late mutation, E. microceras
