Autor: Bruna Coldebella, Rogério Guitarrari Azzone, Luanna Chmyz, Excelso Ruberti, Darcy P. Svisero

Publikováno v: Brazilian Journal of Geology, Vol 50, Iss 1 (2020)

Abstract Oxygen fugacity (ƒO2) conditions were established for Três Ranchos IV (TR-IV, diamond-bearing) and Limeira I (LM-I, barren) kimberlite intrusions, in Alto Paranaíba Alkaline Province, to constrain a possible correlation between fO2 and di

Intensive (P-T-fO2) crystallization parameters of Alto Paranaíba kimberlites and diamond instability: Três Ranchos IV and Limeira I intrusions

Autor: Coldebella, Bruna

Temperature (T), Pressure (P) and Oxygen fugacity (fO2) conditions were established for the Três Ranchos IV (diamond-bearing) and Limeira I (sterile) kimberlites of the Coromandel-Três Ranchos kimberlite field (Minas Gerais and Goiás, Brazil), Alt

The Compositional Evolution of the Phyllosilicates in the Lateritic Profile of the Catalão I Ultramafic Alkaline-carbonatitic Complex (GO)

Autor: Rogério Guitarrari Azzone, Excelso Ruberti

Publikováno v: Geologia USP. Série Científica, Vol 10, Iss 2, Pp 23-43 (2010)

The compositional evolution of the phyllosilicates in the lateritic profile of the Catalão I ultramafic alkaline-carbonatiticcomplex (GO) is proposed in this work based on petrographic and X-ray diffraction analysis, as well as, chemical composition

The Indaiá-I and Indaiá-II intrusions are hypabyssal, small-sized ultrabasic bodies belonging to the Cretaceous magmatism of the Alto Paranaiba Alkaline Province (southeast-central western Brazil). While Indaiá-I is classified as an archetypal gro
