X-ray diffraction (XRD) is one of the most powerful laboratory techniques used in mineralogy to identify minerals and determine their crystal structures. Unlike hand-specimen observations or optical microscopy, XRD examines the arrangement of atoms inside a mineral by...

Thin section mineral analysis is one of the most important laboratory techniques in mineralogy, petrology, and geology. It involves preparing an extremely thin slice of rock—typically 30 micrometers (0.03 mm) thick—and examining it under a polarized light microscope....

Mineral weathering is the natural process through which minerals break down, dissolve, or transform when exposed to Earth’s surface conditions. Minerals that formed deep underground under high temperatures and pressures become unstable when they encounter air,...
