Mineralogy is the branch of the geosciences that investigates the chemical composition, crystal structure, physical properties, and genesis of minerals, which are naturally occurring, inorganic solids with ordered atomic arrangements and defined (though sometimes variable) chemical formulas. It integrates crystallography, solid-state chemistry, and thermodynamics to characterize mineral phases, their stability fields, and phase transitions under varying pressure–temperature–composition conditions. Mineralogical research underpins petrology, ore deposit studies, and environmental and planetary sciences by providing quantitative tools for identifying minerals, modeling geochemical processes, and interpreting rock-forming and alteration histories at microscopic to planetary scales.
Because oxygen-bearing sulfate minerals trap and preserve signals from Earth's atmosphere, scientists closely study how they form. Sulfates are stable over billions of years, so their oxygen isotopes are seen as a time capsule, ...
