106 MESSRS. JUKES-BROWNE AND SCANES ON THE TFeb. I9OI, 



Baycliff Quarry, 



The next good section is furnished by a quarr}'' east of Baycliff 

 Farm and rather more than a mile north-east of Maiden Bradley. 

 This quarry is in a field on the north side of the main road, and the 

 outcrop of the Chloritic Marl runs through the fields on the south 

 side of the road, so that the section commences a few feet below 

 the top of the Greensand. The following beds were exposed in 

 1900 :— 



Feet. Inches. 

 Surface-soil, with large quartz-grains and many angular 



pieces of chert c 1 6 



A. Light bufF-coloured marly silt, enclosing lumps of grey chert 



which break into angular pieces 1 2 



B. Continuous layer of light-grey cherty stone 6 



C. Fine bufF-coloured marly silt, with scattered grains of 



glauconite 2 



1). Hard grey spiouliferous sandstone 6 



E. Greenish-grey glauconitic sand, fine, soft, and laminated ; 



with small irregular spongiform concretions 1 4 



{Large lenticular masses of grey glauconitic and spiculiferous 



sandstone 2 



Irregular seam of yellowish sand and granular sandstone ... 8 



G. Rough granular calcareous and spiculiferous sandstone 1 3 



H. Greenish-grey glauconitic sand, enclosing large irregular 



masses of chert and cherty stone 3 



I. Greyish-white marly silt 1 2 



J. Hard grey granular calcareous sandstone, much like G 1 6

The large quartz-grains in the soil have doubtless come from the disintegra- 

 tion of the sand below the Oornstones. 



Bed A, which underlies the soil at this place, is a light buff- 

 coloured, slightly calcareous silt or sandy marl. It 

 effervesces when touched with acid, but is essentially a mixture of 

 very fine sand and sponge-spicules with a little mica. It encloses 

 lumps of chert, some of which are whitish throughout ; others have 

 a flinty core of solid grey or brown chalcedonic chert ; they are scat- 

 tered through the bed, but do not exceed 6 inches in diameter. This 

 bed we identify with the lower part of Bed 5 at Maiden Bradley. 



Bed C resembles A, but contains a larger proportion of small 

 grains of glauconite. It encloses some small concretions of imper- 

 fect whitish chert, and the following fossils have been found in it : — 



Cardiaster fossarkcs. 

 Discoidea suhucula. 

 Epiaster Lorioli. 

 Holaster Icsvis. 



Pecten orbicularis. 

 P. asper (small and broken). 

 Rhynchonella grasiana. 

 Serpula sp. 



This bed appears to correspond with No. 6 of the Maiden-Bradley 

 section. 



The underlying bed (D) seems to represent N'o. 7 of that section.
