arenaceous

Probably nine tenths of all the coast lines of the open ocean are formed of arenaceous material.

Sand-dunes in deserts or on coasts are unconsolidated arenaceous rock-masses.

Arenaceous Rocks include all sediments in which quartz sand is the most important constituent.

The scenery of its coasts is in part arenaceous plains, and in part arable land, yielding corn to the Indians.

But there are other reasons for the comparative paucity of fossils in arenaceous strata, as we shall see presently.
