164 KUMMEL AND WELLER — LIMESTONES OF KITTATINNY VALLEY 



the date of the folding of these rocks. Slight unconformity hetween the 

 Oneida conglomerate (Shawangunk grit) and the Hudson River shale is 

 shown in the railroad cut at Otisville, New York, a few miles north of the 

 New Jersey state line. This piay mean that some folding took place at 

 the close of tlie Ordovician. • The greater disturbance, however, was un- 

 doubtedly at the close of the Paleozoic. Southeast of the highlands the 

 Triassic rocks rest in part upon the e'roded edges of these early Paleo- 

 zoic formations. The profound faults of the former undoubtedly affect, 

 in some instances, the underlying Paleozoics, but most of the faults in the 

 Paleozoics along the borders of the Trias do not enter the latter, and are, 

 therefore, older. If there was any disturbance in the Kittatinny Valley 

 region during the Trias faulting, we have not been able to differentiate 

 it from the earlier movements.
