GEOLOGY 



TABLE OF THE GEOLOGICAL FORMATIONS OF BERKSHIRE 



In course of time a subsidence of the land took place and the sea 

 again spread over Berkshire, and in so doing no doubt effected consider- 

 able destruction of the older oolitic beds and apparently removed all land 

 or freshwater deposits which may have accumulated during the time of 

 emergence. The result is that our next formation, the Lower Green- 

 sand, rests upon the denuded folds of the Oolite in an unconformable 

 manner. 



Our Lower Greensand is a marine formation, but there was probably 

 land in the western counties, Wales, etc., and also in Kent and Belgium.
