Journal ArticleDOI
A New Understanding of the Provinces of the Amazon Craton Based on Integration of Field Mapping and U-Pb and Sm-Nd Geochronology
João Orestes Schneider Santos,Léo Afraneo Hartmann,Henri E. Gaudette,David I. Groves,Neal J. McNaughton,Ian R. Fletcher +5 more
TL;DR: The interpretation of U-Pb and Sm-Nd isotopic data has led to a new understanding of the subdivision and evolution of the Amazon Craton during Precambrian time, with major improvements and changes made to the previous Rb-Sr based model.
Journal ArticleDOI
The neoproterozoic Mantiqueira Province and its African connections: a zircon-based U-Pb geochronologic subdivision for the Brasiliano/Pan-African systems of orogens
Luiz Carlos da Silva,Neal J. McNaughton,Richard Armstrong,Léo Afraneo Hartmann,Ian R. Fletcher +4 more
TL;DR: The Mantiqueira Province (MPV) is a large, complex structural province deformed by the Neoproterozoic/Early Paleozoic Brasiliano Orogenic event in South America as discussed by the authors.
Journal ArticleDOI
1.6 Ga U-Pb zircon age for the Chorhat Sandstone, lower Vindhyan, India: Possible implications for early evolution of animals
Birger Rasmussen,Pradip K. Bose,Subir Kumar Sarkar,Santanu Banerjee,Ian R. Fletcher,Neal J. McNaughton +5 more
TL;DR: This paper used SHRIMP (sensitive, high-resolution ion microprobe) U-Pb zircon geochronology to date silicified tuffs bounding the Chorhat Sandstone.
Journal ArticleDOI
Advances in SHRIMP geochronology and their impact on understanding the tectonic and metallogenic evolution of southern Brazil
Léo Afraneo Hartmann,Jayme Alfredo Dexheimer Leite,L.C. Da Silva,Marcus Vinicius Dorneles Remus,Neal J. McNaughton,David I. Groves,Ian R. Fletcher,Josiane Santos,Marcos Antonio Zen Vasconcellos +8 more
TL;DR: In this article, the authors used backscattered electron and cathodoluminescence images to understand the evolution of zircons and in understanding the geotectonic and metallogenetic evolution of the complex terrain of southern Brazil.
Journal ArticleDOI
Pre-Variscan geological events in the Austrian part of the Bohemian Massif deduced from U-Pb zircon ages
Gertrude Friedl,Fritz Finger,Jean-Louis Paquette,Albrecht von Quadt,Neal J. McNaughton,Ian R. Fletcher +5 more
TL;DR: In this paper, the authors analysed zircons from 12 rocks (mainly orthogneisses) by means of SHRIMP, conventional multi-grain and single-grain U-Pb isotope-dilution/mass-spectrometry.
