Sediment, as distinguished from sedimentary rock, is a collective name for loose, solid particles and is generally derived from weathering and erosion of preexisting rock. with intercalated intermediate to felsic volcanic rocks and sedimentary rocks (chert and volcaniclastics; Hickman, 1983; Glikson and Hickman, 1981). The tectonic setting of eruption and the magmatic process producing the mafic to ultramafic rocks are controversial; for example, Bar-ley (1993) concluded that the Warrawoona mafic-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.Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. Fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures.
