Geology, petrography and geochemistry of the A-type granites from the Morro Redondo Complex (PR-SC), southern Brazil, Graciosa Province

Autor: FREDERICO C.J. VILALVA, SILVIO R.F. VLACH

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 86, Iss 1, Pp 85-116 (2014)

The Morro Redondo Complex is one of the most important occurrences of the Graciosa A-type Province, southern Brazil. It consists of the Papanduva and Quiriri granitic plutons and a contemporaneous bimodal volcanic association. The Papanduva Pluton in

Micro-structural and compositional variations of hydrothermal epidote-group minerals from a peralkaline granite, Corupá Pluton, Graciosa Province, South Brazil, and their petrological implications

Autor: Silvio R.F. Vlach

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 84, Iss 2, Pp 407-426 (2012)

Epidote-group minerals, together with albite, quartz, fluorite, Al-poor and Fe-rich phyllosilicates, zircon, and minor oxides and sulphides, are typical hydrothermal phases in peralkaline alkali-feldspar granites from the Corupá Pluton, Graciosa Pro

The Serra da Graciosa A-type granites and syenites, southern Brazil. Part 1: regional setting and geological characterization

Autor: Guilherme A.R. Gualda, Silvio R.F. Vlach

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 79, Iss 3, Pp 405-430 (2007)

The Serra da Graciosa region includes important occurrences of granites and syenites of the Graciosa A-type Province (formerly Serra do Mar Suite), southern Brazil. Using fieldwork, petrography, and remote sensing imagery, we characterize the geology
