unstratified

For the present moment it will be enough to consider the two grand divisions—Stratified rocks and Unstratified rocks.

They are rarely, if ever, seen in unstratified rocks; but many layers of stratified rocks abound in these remains.

The orbicular masses often occur in the interior of unstratified mountains, or in the bosom of one bed.

This familiar rock may be studied as an example of the second great group of rocks,—the unstratified, or igneous rocks.

Over much of the northern states there is spread an unstratified stony clay called the drift.
