E.g., marble develops under high pressure Sedimentary Rocks composed of sediments (grains, mud, salts) such as – Clastic: Collection/compaction/cementation of broken up rock pieces. Gypsum – Chemical (Crystalline): Including minerals and chemical salts For this & others, see the st » Gypsum: Calcium Sulfate Dihydrate: CaSO 4.2H2O. Soft rock for artifacts from ancient times. window case on the 1 floor Founders North building – Organic: Calcium from animal bones can combine with organic materials (proteins). » Proteins Amino acids including carbon (C), hydrogen (H), oxygen (O) & nitrogen (N). ← Volcanic Body fat is complicated Rock Metamorphic Clastic Chemical Sedimentary Organic CH Carbon-Carbon 2 bond Carbon- Nitrogen C bond C N Acidic Amino part COOH part NH2 Limestone, seashells Simple amino acid Sandstone, sand grains Rich in Calcite CaCO 3 Glycine NH2CH2COOH Shale, mud particles .edu /~ Page metin 3 utdallas Sedimentary Rocks and Shield v Sedimentary rock layers are on top of each other. Often sandstone is above shale which is above limestone. E.g., layering of rocks in Tulsa Densities of these are close 1.85-2.36 tons/yard3=2.4-3.1 tons/m3 Sandstone However, layering sequence of rocks on top of each other Shale Limestone depends on depositional sequence and materials, and can also be Basement rock altered by tectonic plate movements and earthquakes.
