marlstone, with black marl separating 

 them, and traversed like the beds 

 above and below *by thin veins of 

 gypsum _ 



Marlstones, grey, separated from the" 

 bed below by marl, green in the lower 

 portion, black in the upper (7 inches), 

 passing up into less massive grey marl- 

 stones mixed with much more black J>9 

 marl containing pink gypsum, and 

 lastly— at the top — into a black shaly 

 deposit, in which marlstones are sub- 

 ordinate and there is more gypsui 



Two massive beds of greenish-grey "V 

 marlstone and much pink gypsum. ( „ 

 These are the two bands so conspicuous C 

 in Blue Anchor Point J 



Grey nodular marlstones, with black") 

 shaly marl, much pink gypsum, and > 4 

 veins of white gypsum ) 



Marl, green, with some pink gypsum") 

 and a very regular layer of white (q 

 fibrous gypsum. Below this are veins t 

 of pink gypsum obliquely arranged ... j 



Seven layers of somewhat nodular green O 

 ish-grey marlstone interbanded with 

 black shaly marl, which has running in 

 it layers of gypsum mainly in a hori- 

 zontal position, while the pink layers 

 are in the main obliquely arranged, i 

 The topmost marlstone is more regular, | 

 conspicuous, and of a lighter colour ...J 



Marlstone, hard, dirty, yellowish-grey, } -, 

 gypsiferous at the top , ) 



Dark green marl, with a thin but con- ^ 

 spicuous layer of white gypsum near > 1 

 the top J 



Marl, blackish, with a green tinge and" 

 a faint red zone near the base. It is 

 traversed by one very conspicuous layer 

 of white fibrous gypsum and also by 

 oblique and ramifying veins of pink. 

 At the top is a noticeable zone of pink 

 gypsum in green marl, overlain by 

 blackish marl that fills up the irregu- 

 larities in the hard layer of gypsum 

 below
