ORIGIN OF THE TRIASSIC TROUGH OF CONNECTICUT 699 



However, the description of the geology of the Vale of Eden sug- 

 gests a possible problem in sedimentation. A detailed study of the 

 rocks of the eastern upland near the fault zone, combined with a 

 microscopic study of the Anterior, Posterior, and Upper sandstones 

 of the Connecticut Valley deposits might yield further evidence 

 of the progressive growth of the eastern fault during the period of 

 sedimentation.
