A Catalog of Analyzed Calciferous and Subcalciferous Amphiboles Together with Their Nomenclature and Associated Minerals

A catalog is presented of 1217 post-1890 published amphibole analyses which contain 6.00 per cent or more of CaO. Of these, 1106 are accompanied by at least one refractive index, an optic angle, or a density determination. With each analysis is given these physical constants; as well as the half-unit cell contents calculated on the basis of 24 (O, OH, F, Cl); the reference source; the locality; the mineral assemblage in which the amphibole occurs; whether any coexisting minerals have been analyzed; an indication of the quality of the analysis; and, to each amphibole, a name which conveys the composition rather precisely.
