Sedimentary Rocks
Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.. Erosion and weathering include …

A clastic sedimentary rock. Sandstone contains sand-sized clasts, is most easily identified by its "sandpaper" feel. Sandstone usually appears as a uniform accumulation of cemented sand, which can vary in color as pink, gray, or beige. Desert environments, as well as beaches, reliably deposit sandstone.

Rock Cycle Diagram. Rocks are broadly classified into three groups: igneous, sedimentary and metamorphic, and the simplest diagram of the "rock cycle" puts these three groups in a circle with arrows pointing from "igneous" to "sedimentary," from "sedimentary" to "metamorphic," and from "metamorphic" to "igneous" again.

4.3.1 Clastic Sedimentary Rocks. Weathering and erosion occur normally in areas that are at high elevation, such as mountains, while deposition occurs in lower areas such as valleys, lakes, or the ocean. The sediment is transported from the area of erosion (e.g. the "source") to area of deposition (e.g. the "sink") by ice, water, or air.

Most rocks will simply feel coarse or rough, but if you feel something different be sure to make a note of it. Some rocks may feel glassy, slippery, greasy, or gritty.

The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.

The concept of the rock cycle is attributed to James Hutton (1726–1797), the 18th-century founder of modern geology. The main idea is that rocks are continually changing from one type to another and back again, as forces inside the earth bring them closer to the surface (where they are weathered, eroded, and compacted) and forces on the earth ...
