GEOLOGICAL DISTRIBUTION OF CLAY. 



The clays of New Jersey belong to a wide range of geological 

 formations, occurring in fact in nearly all the larger geological 

 subdivisions in the State. They are not all of equal value, how- 

 ever, and in the following table, which shows the major geologi- 

 cal subdivisions of the State, only the important clay-bearing 

 members are indicated by the asterisk. Small clay deposits, some 

 of which are worked, occur in most of the other groups, as will 

 he shown in the following pages.
