Unformatted text preview: 5-Part Definition of a Mineral 1. Naturally occurring: not synthetic 2. Inorganic: not alive, never was 3. Solid: not liquid or gas 4. Specific chemical composition or range of compositions: NaCl, FeS2, (Mg, Fe)2SiO4 5. Regular internal atomic arrangement (crystalline structure): constituent atoms/ions are symmetrically arranged in a three-dimensional lattice with a specific shape Ex.) ice is not a mineral because it does not take a symmetrical shape each time; it takes the shape of the container it is in Mineral Physical Properties: o Color o Hardness o Density (mass/volume) o Shape o Cleavage and fracture o Luster o Streak o Reaction with dilute hydrochloric acid: solubility o Others: taste, appearance in UV light, magnetism, etc Common Rock Forming Minerals: o Feldspars: Na, Ca, K, Al, silica o Quartz: SiO2 o Pyroxenes: Ca, Mg, Fe, silica (dark green color) o Amphiboles: Na, Ca, Mg, Fe, Al, silica, water o Micas: K, Al, silica, water o Clay Minerals: Al, silica, water o Olivine: Mg, Fe, silica Rock: a solid, cohesive aggregate of minerals or mineral-like materials o 3 Types: Igneous (original rock), sedimentary, metamorphic o All rocks contain information regarding their formation What determines igneous rock type? Cooling history: Magma composition: 3 Types of Sedimentary Rocks: Clastic: formed from weathered bits of pre-existing rocks Chemical: formed by precipitation of minerals from solution Biochemical: formed by biologically-mediated precipitation of minerals from solution (sea water). Metamorphic Rocks: igneous or sedimentary rocks that are subject to immense heat and pressure ...
