TL;DR: In the past years, the study of the continental flood volcanism in the Parana basin had been mainly concentrated in the southern regions, where thick lava sequences are well exposed as mentioned in this paper, which essentially concerned basic geology, petrography, radiometric dating and, subordinately, petrochemistry, isotope geochemistry and paleomagnetism.

Petrology of Serra Geral (Paraná) continental flood basalts, southern Brazil: crustal contamination, source material, and South Atlantic magmatism
TL;DR: The Serra Geral (Parana) continental flood basalt (SG-CFB) province in Brazil is associated with the Jurassic-Cretaceous breakup of Gondwanaland and the transition of continental to oceanic magmatism during the opening of the South Atlantic Ocean as discussed by the authors.

Petrology and geochemistry of the Neoproterozoic Guaxupé granulite facies terrain, southeastern Brazil
TL;DR: In this article, geochemical and oxygen isotope data on the Neoproterozoic granulite facies rocks (enderbites, charnockite and charnokitic augen gneisses) of Guaxupe, Brazil are assembled.

The Juiz De Fora Granulite Complex of the Central Ribeira Belt, SE Brazil: A Paleoproterozoic Crustal Segment Thrust During the Pan-African Orogeny
TL;DR: The granulites of the Juiz de Fora complex occur within thick basement thrust slices associated with the Pan-African shortening process in the central segment of the Ribeira belt as mentioned in this paper.

O Complexo Juiz de Fora na região de Três Rios (RJ): litogeoquímica, geocronologia U-Pb (LA-ICPMS) e geoquímica isotópica de Nd e Sr
TL;DR: The Juiz de Fora Complex as discussed by the authors consists of rocks with a wide range of composition, from granitic to basic terms, and based on lithogeochemical studies, it was possible to subdivide this unit into four associations: (i) high-K calc-alkaline, (ii) medium-k calcalkaline, (iii) tholeiitic and (iv) alkaline).
