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.
Water is ubiquitous on Earth—about 70% of Earth's surface is covered by the stuff. Water is in the air, on the surface and inside rocks. Geologic evidence suggests water has been stable on Earth since about 4.3 billion years ...
