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.
Earth's earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests.

Rocks can bind carbon dioxide—and much faster than previously thought. For a long time, it was assumed that the transformation of CO2 into carbonate rock depends on very slow, time-consuming processes. According to that view, ...
