GEO 102 Study Guide - Midterm Guide: Mica, Gneiss, Breccia
Document Summary
Materials such as, gravel, sand, mud, and lime that is transported by wind, water, ice, or gravity; material that is precipitated from a solution; deposits of organic origin like coal or coral reefs. What is the difference between a sediment and a sedimentary rock? sediments: see definition above, they are what make up sedimentary rock sedimentary rock: rock formed by the accumulation and consolidation of sediment. What are the textures of sedimentary rocks? size, shape, and distribution of particles that collectively make up the rock: size: gravel, sand, mud, roundness: the shape of the sediment grains and is related to the distance a sediment has been transported, sphericity: how close to a spherical shape a grain is or will be, sorted: sediments with a small range of grain size are sorted well. Inorganic process: chemical mainly carbonates (limestone, coquina) only, no biological activity involved terrestrial evaporates: marine whitings.
