Timing of mafic magmatism in the Tapajós Province (Brazil) and implications for the evolution of the Amazon Craton: evidence from baddeleyite and zircon U–Pb SHRIMP geochronology
TL;DR: In this article, a new SHRIMP U-Pb baddeleyite and zircon ages and the reinterpretation of 207 existing dates indicate one orogenic (Ingarana) and four postorogenic (Crepori, Cachoeira Seca, Piranhas, and Periquito) basaltic events in the Tapajos Province, south central Amazon craton.
Journal ArticleDOI
Gold in the Neoproterozoic juvenile Bossoroca Volcanic Arc of southernmost Brazil: isotopic constraints on timing and sources
Marcus Vinicius Dorneles Remus,Neal J. McNaughton,Léo Afraneo Hartmann,Jair Carlos Koppe,Ian R. Fletcher,David I. Groves,Viter Magalhães Pinto +6 more
TL;DR: The Bossoroca gold deposit as mentioned in this paper consists of veins and stockworks of quartz-gold ores with minor pyrite, chlorite, sericite and tourmaline are the main gangue minerals.
Journal ArticleDOI
Archaean carbon reservoirs and their relevance to the fluid source for gold deposits
TL;DR: Barley and Groves as mentioned in this paper showed that seafloor alteration and fault-controlled regional alteration have completely different carbon isotope compositions, and showed that the mere existence of two carbon-in-carbonate reservoirs and variation in carbon- isotope ratios of carbonates between individual gold deposits in one area, negate some of the fundamental assumptions used to support magmatic-fluid models.

Deepest exposed crust of Brazil-SHRIMP establishes three events
Léo Afraneo Hartmann,Jayme Alfredo Dexheimer Leite,Neal J. McNaughton,João Orestes Schneider Santos +3 more
TL;DR: The deep exposed crust of Brazil is in the western portion of the exposed Precambrian shield of southernmost Rio Grande do Sul State and comprises a bimodal sequence of mafic garnet granulites and metatrondhjemites, intercalated with smaller volumes of metamorphosed pyroxenites, anorthosites, sillimanite gneisses, and banded iron formation as mentioned in this paper.
Journal ArticleDOI
Zircon U–Pb SHRIMP dating of gneissic basement of the Dom Feliciano Belt, southernmost Brazil
Jayme Alfredo Dexheimer Leite,Léo Afraneo Hartmann,Luís Alberto D'Ávilla Fernandes,Neal J. McNaughton,E. Soliani,Edinei Koester,João Orestes Schneider Santos,Marcos Antonio Zen Vasconcellos +7 more
TL;DR: The age of a basement gneiss of the Dom Feliciano Belt along the coast of Rio Grande do Sul has been determined by zircon U-Pb SHRIMP to be about 2.08-Ga for the K-granitic magmatism and 800-590-Ma for the associated low-angle and sub-vertical shear zone deformations as discussed by the authors.
