Rock Identification Tips. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or claylike layers (strata). They are usually brown to gray in color and may have fossils and water or wind marks. Metamorphic rocks such as marble are tough, with straight or curved layers (foliation) of light and dark minerals.
