Abstract The study of magnetic fabrics and rock magnetic properties, together with geological and structural mapping, was carried out in a syenite pluton to investigate its shape and emplacement history. The Piquiri Syenite Massif (PSM) is an alkaline pluton which exhibits S >> L magmatic fabric and is interpreted to be part of the last Neoproterozoic post-collisional magmatic episodes in southernmost Brazil. Thermomagnetic curves, hysteresis data and coercivity spectra obtained from representat...

Abstract The post-collisional stage of the Brasiliano/Pan-African Cycle in Southern Brazil is marked by metaluminous and peraluminous granites controlled by a transcurrent shear zone system. In southernmost Brazil, the sinistral, NE-trending Dorsal de Cangucu Transcurrent Shear Zone (DCTSZ) is the best known structure that conditioned these peraluminous granites. Despite its poorly-developed linear fabric, the emplacement of the NNW-elongate Butia Granite (BG) northwest of the DCTSZ is interpret...
