Base of quarry. 



(K) Bladon Quarry, near Woodstock. 



This section exposes the Forest Marble, capped by a rubbly 

 subsoil of Cornbrash, in which fossils are not so numerous as in 

 most of the other exposures; this subsoil is from 1 to 4 feet thick. 

 The section of the Forest Marble is as follows : — 



Thickness in feet. 



Bed a. Somewhat marly, false-bedded, oolitic limestones 2^ 



Bedi. Blue -clay 2 



Bed c. Somewhat marly, false-bedded, oolitic limestones 3 



Bed d. Blue compact limestones 1 



Bed e. Blue clay 3 



Bed /. Blue argillaceous limestone (recognizable in the Hanhorough 

 Well -section). Bhynchonellce and spines of Echini are 



abundant 1 



Hedg. "Very hard, compact, blue-hearted limestone, in three bands, 



showing the false bedding only after prolonged weathering.! 14 



Bed h. Blue clay about 3 2 



The thicknesses are considerably greater than in any of the 

 Forest-Marble exposures on the east. 



(i) Haiiborough Quarry (at the cross-road to Eynsham, 

 east of the Railway-Station). 



About 2 feet of rubbly, very fossiliferous Cornbrash forms the 

 subsoil of this section. 



The Forest Marble consists of 4 feet of blue clay, resting upon 

 compact, shelly, oolitic limestones, in which the false bedding is 

 apparent only after prolonged weathering : the thickness of 

 limestone exposed does not exceed 10 feet.

2 [A well now being sunk within 200 yards of the quarry lias shown that the 

 thickness of clay is very irregular, varying from 2§- to 4 feet, the lower part 

 being very marly. The clay rests upon an extremely irregular surface of the 

 Fossiliferous Cream-Cheese Bed, which is here about 12 inches thick ; this rests 

 upon marly limestones, of which only a thickness of 2 feet has at present been
