?Geology of a quartz body at the Estación Pablo Acosta area, Azul, Tandilia System basement?. Among the several outcrops of the mainly Palaeoproterozoic igneousmetamorphic basement of the Tandilia System exposed near the Estación Pablo Acosta, a quartz body, associated to a NE-SO shear zone, was identified. Field work, petrologic and geochemical studies revealed that it was formed from a siliceous fluid generated by metamorphic differentiation during the Transamazonian orogeny. On the other hand, the high degree of quartz purity together with the estimated outcropping volume points out a potential importance for industrial commercialization of the mineralization. In addition, this research provides valuable information to the geological-genetic model for the Tandilia System of the Buenos Aires Province.
