In the Atlas of Ore Minerals, the authors focus on the mineral species encountered in ore deposits of the Republic of Argentina, many of them of epithermal type. They describe 210 ore minerals, illustrate their associations, both with macrophotos and in reflected light, and document their chemical composition. Enlightened interpretations of textural features hold the key to the establishment of paragenetic sequences. They include an account of the tectonic evolution of Argentina and describe the more unusual mineral deposits, like Pirquitas, Famatina, Capillitas, Quevar and Tumiñico, all characterized by very complex assemblages, including selenides in some cases. The 400-page book is published with a DVD-ROM of all mineral photos as a resource to teachers, students, and researchers.
