Sandstone: Sedimentary Rock Pictures, Definition
To a geologist, the word "sand" in sandstone refers to the particle size of the grains in the rock, rather than the material of which it is composed. Sand-size particles range in size from 1/16 millimeter to 2 millimeters in Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks.
