Descriptions
Groundmass glass, phenocrysts, microphenocrysts, and microlites of glass shards (1011 analyses at single points), feldspars (568), biotites (183), Fe–Ti oxides (101), amphiboles (30), and pyroxenes (14) were analysed on polished thin sections of Holocene volcanic ashes, ignimbrites and lava domes of Southern Puna and neighbouring areas (NW Argentina) by electron probe microanalyser (EPMA). The quality of mineral analyses was reviewed, verifying that the structural formula gave a correct stoichiometry with specific measuring programs for feldspars, biotite, Fe–Ti oxides, pyroxene, and amphibole. Geothermobarometry was constrained using the chemistry of feldspars, Fe–Ti oxides, clinopyroxene, and amphibole. The studied volcanic materials are mainly associated with the 4.2 ka cal BP eruption of the Cerro Blanco Volcanic Complex.
Analytical results were determined by a CAMECA SX-50 and a JEOL JXA-8230 electron probe microanalysers (EPMA) at the EPMA Laboratory of the CCiT services of the University of Barcelona. The instruments were calibrated using primary natural and synthetic standards. The quality of mineral analyses was reviewed, verifying that the structural formula gave a correct stoichiometry, with specific measuring programs for feldspars, biotite, Fe–Ti oxides, pyroxene, and amphibole.Contact person: Fernandez-Turiel, J.
