These unstratified rocks are the material of all our quarries and great rocks.
unstratified Rocks may be divided into two distinct classes.
The stratified thus succeeded to the unstratified, and something like variety was established.
The boulders of Erreré do not rest on the stratified sandstone of the Serra, but are sunk in the unstratified mass of the clay.
They are rarely, if ever, seen in unstratified rocks; but many layers of stratified rocks abound in these remains.
To this unstratified form of the deposit, the name of till has been applied in Scotland.
They also are seen, in some instances, to pass insensibly into the unstratified division of a, or the Plutonic rocks.
Finally, over the undulating surface of the denuded sandstone an ochraceous, unstratified sandy clay was deposited.
They are unstratified,—not in layers or strata, but in a formless mass,—and in this they differ from water-formed rocks.
Most of these deposits were unstratified, but distinct stratification was far from uncommon.
