FERRI-OTTOLINIITE AND FERRIWHITTAKERITE, TWO NEW END-MEMBERS OF THE NEW GROUP 5 FOR MONOCLINIC AMPHIBOLES

Oberti R.; Cámara F.; Caballero J.M. (2004)

Mineralogical and crystal-chemical descriptions are provided for two end-members of the new Group 5 introduced by Leake et al. (2004) in the nomenclature of amphiboles. This new classification scheme recognizes the occurrence ...
LITHIUM IN AMPHIBOLES: DETECTION, QUANTIFICATION, AND INCORPORATION MECHANISMS IN THE COMPOSITIONAL SPACE BRIDGING SODIC AND BLI-AMPHIBOLES

Oberti R.; Cámara F.; Ottolini L.; Caballero J.M. (2003)

Lithium is an important constituent in amphiboles, where it can be incorporated up to a limit of three atoms per formula unit (apfu). Lithium can partition itself between the B-group sites (where it occurs at the [6+2] ...
SODIC-FERRI-FERROPEDRIZITE AND FERRI-CLINOFERROHOLMQUISTITE: MINERAL DATA AND DEGREE OF ORDER OF THE A-SITE CATIONS IN LI-RICH AMPHIBOLES

Oberti R.; Cámara F.; Ottolini L.; Caballero J.M. (2003)

A systematic examination of metamorphic episyenites in the Pedriza Massif, Sierra de Guadarrama, Spain, allowed detection of two more distinct Li-rich C2/m amphibole species. They can be related to previously described ...
