FENNER. THE WATCHUNG BASALT 187 



Comparison was made between the Watchung deposit and similar 

 mineral formations elsewhere. In some cases, there was evidence that 

 conditions during the formation of zeolites were different, or that the 

 subsequent history had effected changes which made impossible a strict 

 comparison with the Watchung rocks. In most cases, however, judging 

 from the rather scanty evidence available, conclusions regarding sequence 

 are confirmed.
