Amphiboles
This site provides a detailed look at the crystal structure and compositional variations of amphiboles. Also discussed are ways to assess the quality of analyses from looking at the stoichiometry of mineral formulas, how to estimate ferric iron, and special considerations affecting formula recalculation. A 3-D model of the mineral's structure is also included.
