Sometimes the boundaries with adjoining formations are obvious, such as when they are marked by obvious differences in rock type (i., limestone vs. shale), while in other cases, only the presence or absence of certain fossils marks where one formation ends and another starts.Figure 5.3.1 5.3. 1: Enlarged image of frosted and rounded windblown sand grains. Medium-grained rocks composed mainly of sand are called sandstone, or sometimes arenite if well sorted. Sediment grains in sandstone can having a wide variety of mineral compositions, roundness, and sorting.For example, Figure 1 shows a sequence of limestone, shale, and sandstone. Limestone forms in a deep marine environment from precipitation of calcium carbonate. Shale is made of fine clay particles, and therefore indicates deposition in relatively still water.Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. From German Schalstein laminated limestone, and Schalgebirge layer of stone in stratified rock.Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles.
