The Troia–Pedra Branca complex is the most extensive exposure of mafic–ultramafic rocks in the Borborema Province, northeastern Brazil. Chromitite occurrences in this unit are known for a long time, particularly because of its platinum group elem

Point and imaging spectroscopy investigations on the Pedra Branca orogenic gold deposit, Troia Massif, Northeast Brazil: Implications for mineral exploration in amphibolite metamorphic-grade terrains

Autor: João L. C. Naleto, Mônica Mazzini Perrotta, Felipe Grandjean da Costa, Carlos Roberto de Souza Filho

Publikováno v: Ore Geology Reviews. 107:283-309

The Pedra Branca gold deposit is a recent discovery conducted by private exploration companies in the Troia Massif of the northern Borborema Province, Northeast Brazil. It comprises an orogenic gold deposit hosted by the amphibolite-facies Serra das

Geochemistry and U–Pb–Hf zircon data for plutonic rocks of the Troia Massif, Borborema Province, NE Brazil: Evidence for reworking of Archean and juvenile Paleoproterozoic crust during Rhyacian accretionary and collisional tectonics

Autor: João L. C. Naleto, Rafael Guimarães Correa Lima, Marco Antonio Galarza, Jean M. Lafon, Joseneusa Brilhante Rodrigues, João Marinho Milhomem Neto, Evandro Luiz Klein, Felipe Grandjean da Costa

Publikováno v: Precambrian Research. 311:167-194

Rhyacian (c. 2.30–2.05 Ga) subduction-accretion and collisional processes are thought to represent an important event of crustal growth and reworking, often reported in the so-called Tranzamazonian/Eburnean granite-greenstone terranes of N/NE Brazi
