WAVERLY SERIES OF CENTRAL OHIO 



213 



Ohio. The upper part of the series he correlated with the for- 

 mations of the Mississippi valley and two quite persistent con- 

 glomerate horizons were named Conglomerate I and II. 1 

 The classification is as follows : 



Cuyahoga or 

 Waverly series 



Logan 



\ 



(Conglomerate II) 

 j Kinderhook, 50-60 ft. 

 (Conglomerate I) 



( Waverly shale, 40 ft. 

 I Berea shale, 200-400 ft. 

 - Berea grit, 50-60 ft. 



Bedford shale, 50 ft. 



Cleveland shale (local), 50 ft. 



Keokuk, 



100-150 ft. 

 Burlington 



Berea or Tran- 

 sition series 



( Western equiva- 

 lent of Upper 

 Chemung) 



Erie shale, 



Eastern or typical Chemung (lower part), 100 ft. 2 



In the above classification the Berea shale included Dr. 

 Orton's Berea shale and all of his overlying Cuyahoga shale 

 except its fossiliferous upper 40 feet which, extending to the 

 base of Conglomerate I, was called the Waverly shale. 



In 1889 Dr. Newberry stated that the Waverly group " where 

 best seen, as in northeastern Ohio, .... is about 500 feet 

 thick, and fills the interval between the Erie shale (Chemung) 

 below and the Carboniferous conglomerate above." 3 The fol- 

 lowing classification of the Waverly group was given :

4. Bedford shale -
