The Perjatay conglomerate is held to be the same
as the Dighton conglomerate, the terminal member of
the Pennsylvanian. As no bedding is to be seen
here it may be that the deposit is here also a
lithite. The stretched condition of the rocks of course
makes it look very different from a till. There is
however almost no stratification to be seen.
He then continued back to Fitchburg, near
River to Driscoll's to see some Dighton conglomerate.
Here it is far less squeezed than at Ashputt
but more than at Fresh Hill Cemetery. At Driscoll's
we also saw what I consider showing that the dip
was about 45 degrees or more. Considerable solidification
is developed here.
Then on to Worcester, Dighton, Taunton,
Randolph where the forces are made upon joint
fill and coarse sandstone. These are the basal
beds flanking the south side of the Blue Hills.
In color they remind of the iron outcrops but are by no means so red, nor is there any quartz here.
