IN THE ANGLO-PARIS BASIN 19 



by Hill with that of the Maidstone By-Pass (Owen i960 ; 369-371 and text-fig. 6 

 herein) it can be seen that the sequence exposed at Eyhorne Street included parts of 

 the equivalent of Divisions B and C which appear to be identical to that of the By- 

 Pass. 



There is nothing further to add to my account of the sections exposed during the 

 construction of the Maidstone By-Pass motorway (M20) (Owen 1960), except for an 

 unfortunate omission of a complete sentence in my reply to the discussion of my 

 paper by Gray (1962 ; 469). The missing sentence read, ' As seen in the sections, the 

 Tertiary faulting affects the beds [in the A 249 clover-leaf] in the following manner.' 

 Without this sentence there is the implication that the faulting is intra-Albian which 

 it certainly is not. The correlation of the sections is shown in text-fig. 3, and it can 

 be seen that the stratigraphical succession is very uniform. 



(iii) MEDWAY TO TROTTISCLIFFE 

 (a) Paddlesworth 



West of the Medway, the outcrop changes direction through an arc of about 12 but 

 no complete sequence is seen until one reaches the Ford Place clay-pit, Trottiscliffe, 

 where the Middle Albian sequence is thicker than at the Maidstone By-Pass. How- 

 ever, in the early months of 1968 the Associated Portland Cement Manufacturers 

 clay pit at Paddlesworth, which has for many years shown an important Upper 

 Gault sequence, was cut further south exposing the higher part of the Lower Gault. 

 The Middle Albian sequence is shown in text-fig. 7, and its correlation with the 

 Maidstone By-Pass and Ford Place in text-fig. 3. The basic similarity with the 

 sequence at Ford Place from the middle of Division 4 permits the use of the same 

 divisional enumeration. 



By analogy with Ford Place, the 3 feet 6 inches (1-067 m -) °f clays at the top of 

 Division 4 at Paddlesworth are almost certainly of subdelaruei Subzone age. They 

 contain numerous Inoceramus concentricus and Hamites tenuicostatus as at Ford 

 Place, but no specimens of Mojsisovicsia are yet to hand. These clays represent an 

 expansion of nodule bed C (ii) at the Maidstone By-Pass. Bed 5 (i) contains a 

 typical meandrinus Subzone fauna and the sediments up to the top of 5 (vii) are also 

 classified with this Subzone. 5 (i) corresponds exactly to 5 (i) at Ford Place but does 

 not contain phosphatised fossils with the shell preserved as at the latter locality. 

 5 (ii-vi) correspond to 5 (ii-iv) at Ford Place and 5 (vii) is the direct equivalent of 

 5 (v). In general the sequence is slightly thinner at Paddlesworth than at Ford 

 Place, but it is much thicker than that seen at the Maidstone By-Pass where the 

 equivalent sediments are but 2 feet 7 inches (0787 m.) thick. 



The sediments of lautus-Zone age at Paddlesworth 5 (viii) are 2 inches (0-051 m.) 

 thicker than at Ford Place 5 (vi), and 1 inch (0-025 m -) thinner than at the Maidstone 

 By-Pass. Part phosphatised fossils occur at the base of 5 (viii) and the species of 

 Euhoplites indicate the nitidus Subzone, although the commonest ammonite is 

 Dimorphoplites biplicatus (Mantell). Crushed Anahoplites planus occur in the top 

 few inches, and there are a few uncrushed Euhoplites truncatus in the uppermost inch.
