Petrogenesis of coexisting SiO2-undersaturated to SiO2-oversaturated felsic igneous rocks: The alkaline complex of Itatiaia, southeastern Brazil
Pietro Brotzu,Celso B. Gomes,Leone Melluso,L. Morbidelli,Vincenzo Brescia Morra,Excelso Ruberti +5 more
TL;DR: The Itatiaia alkaline complex is a Late Cretaceous intrusion (72 Myr) made up of felsic differentiates, with syenitic rocks dominant throughout and with presence of both nepheline- and quartz-rich varieties as discussed by the authors.

Petrography and mineral chemistry of carbonatites and mica-rich rocks from the Araxá complex (Alto Paranaíba Province, Brazil)
Gianbosco Traversa,Celso B. Gomes,P. Brotzu,Nicoletta Buraglini,L. Morbidelli,M. S. Principato,Sara Ronca,Excelso Ruberti +7 more
TL;DR: The Araxa complex as discussed by the authors comprises carbonatites forming a central core and a complex network of concentric and radial dykes as well as small veins; additionally, it includes mica-rich rocks, phoscorites and lamprophyres.
U–Pb ages, Sr–Nd- isotope geochemistry, and petrogenesis of kimberlites, kamafugites and phlogopite-picrites of the Alto Paranaíba Igneous Province, Brazil
Vincenza Guarino,Fu-Yuan Wu,Michele Lustrino,Leone Melluso,Pietro Brotzu,Celso B. Gomes,Excelso Ruberti,Colombo Celso Gaeta Tassinari,Darcy P. Svisero +8 more
TL;DR: The kimberlites, kamafugites and phlogopite-picrites of Alto Paranaiba Igneous Province (APIP), southern Brazil, span a range between ~91 and 78 Ma with new in-situ, more tightly constrained U-Pb ages as discussed by the authors.

Hydrothermal ree fluorocarbonate mineralization at barra do itapirapuã, a multiple stockwork carbonatite, southern brazil
TL;DR: The Barra do Itapirapua (BIT) carbonatites in southern Brazil belong to the final stages of the Early Cretaceous alkaline rock as discussed by the authors, and are known as carbonatite magmatism of the Ponta Grossa Arch Province.
