CEETACEOUS AND TEETIAET FORMATIONS OF NEW JERSEY. XI 



termediate beds wliicli lie Immediately over 

 these, and as far as seen, with the same gen- 

 eral dip, though a little smaller in amount, 

 are rich in marine fossils which are unques- 

 tionably of the Cretaceous period 



The numerous beds and strata of the g" 



series all dip gently to the southeast, the -^ 



descent being not more than ftO feet per mile ; |" 



while the underlying red sandstone dips m 



towards the northwest at an angle of 10° or ^ 



12°. I

The accompanying section, Fig. 1 , across g 



the Cretaceous and Eocene strata in I\Iiddle- % 



sex and Monmouth Counties, in which part « 



of the State the}^ are best exposed, will sulii- I 



cientlv illustrate their mode of occurrence. S" 



The columnar section, Fig. 2, will further a 



show the thickness of the Cretaceous and § 



Eocene strata, as far as present demonstra- ^ 



tions extend ; and the ma}) of the part of New | 



Jersey in which these strata are found will '^■ 



make plain the numerous references to local- i. 



ities, which are given in the descriptions of ^ 



species. In addition to the outcrop as given ^ 



on the map, and the dip as shown in the i 



section, the correctness of the columnar -A 



o 



section has been proved by the borings in ^, 



several artesian wells in which the successive ^ 



strata of greensand, clay, etc., have been met ^ 



in the order hei*e laid down. The Miocene I 

 is found, with its characteristic fossils, in 

 several isolated localities in the counties of 

 Cumberland and Salem, but no structural 

 or other well-marked geological peculiarities 

 of these beds have yet been developed.
