New petrostructural data are presented from the southeastern Quadrilátero Ferrífero, a distinct polyorogenic domain of the São Francisco Craton characterized by granite-gneiss domes and keel structures. The Minas Supergroup of Siderian age that hosts a huge volume of ferriferous sediments was deposited on the flat and eroded surface of the Archean...

Abstract In this contribution we investigate the exhumation T-t path of a nappe system located in the southernmost edge of the Brasília Orogen, southeast Brazil, developed during the West Gondwana assembly. The allochthons represent an inverted metamorphic pile of nappes and were deformed during the collision between the Paranapanema (active margin...

Termocronologia é uma técnica que aplica sistemas químicos e isotópicos para extrair informações sobre a história termal de um terreno geológico. O conhecimento da história termal, associado a outras informações geológicas, permite estabelecer a duração/idade de processos geológicos-chave para o entendimento da evolução da história da Terra. Neste...
Article
Combining U-Pb geochronology and trace element characteristics of accessory minerals more reactive during metamorphism and deformation than zircon, such as titanite (CaTiSiO5), is a powerful tool for elucidating pressure-temperature-time (P-T-t) evolution of orogenic basement complexes. This study reports in-situ titanite U-Pb and trace element dat...

The Liberdade and Andrelândia nappes, SE Brazil, record the western Gondwana amalgamation in the Southern Brasília Orogen during the Ediacaran. The Liberdade Shear Zone acted as the boundary between these two overlapping nappes. Quartz c-axis fabrics and strain data from quartzite samples and petrological data from hosting metapelite rocks were ana...

Caracterização geométrica e cinemática da Zona De Cisalhamento Major Gercino e sua importância na compartimentação dos terrenos Pré-cambrianos de Santa Catarina
Article
Sedimentary basins are, in many cases, the only preserved record of the geological processes active through geological time. These deposits preserve age, isotopic and geochemical signatures of the source rocks, providing insights into tectonic setting. In this context, we investigate the lithostratigraphy, provenance and tectonic environment of the...

The Piancó-Alto Brígida branching system of orogens (SPAB) is in the central and center-western part of the Transversal Zone, of Borborema Province, in the states of Paraíba, Pernambuco and Ceará. It is a final tectonic product of an oroge-netic development during Cryogenian-Ediacarian periods. The original paleogeographic (and lithostratigraphic)...

An inventory of geological sites based on solid and clear criteria is a first step for any geoconservation strategy. This paper describes the method used in the geoheritage inventory of the State of São Paulo, Brazil, and presents its main results. This inventory developed by the geoscientific community aimed to identify geosites with scientific va...

We report a study integrating 13 new U–Pb LA-MC-ICP-MS zircon ages and Hf-isotope data from dated magmatic zircons together with complete petrological and whole-rock geochemistry data for the dated granitic rocks. Sample selection was strongly based on knowledge reported in previous investigations. Latest Devonian–Early Carboniferous granite sample...

Closure of the southern Adamastor Ocean led to the development of the Neoproterozoic-Early Cambrian orogens on both margins of the present South Atlantic Ocean, which preserve a rich record of West Gondwana assembly and large-scale crustal evolution. Here we describe the distinct stages and tectonic regimes related to the evolution of the southern...
Article
The late Neoproterozoic processes of western Gondwana assembly are well-preserved in most Brazilian orogens. In the southern edge of the São Francisco Craton, a syn-metamorphic pile of nappes is the result of the closure of the Goiás-Pharusian Ocean through the collision between the São Francisco (passive margin) and Paranapanema (active margin) pa...
Article
Carboniferous igneous activity in the Sierra de Velasco (NW Argentina) led to the emplacement of several magmas bodies at shallow levels (< 2 kbar). One of these, the San Blas intrusive complex formed over millions of years (≤ 2-3 m.y.) through three periods of magma additions that are characterized by variations in magma sources and emplacement st...

Article
Early Proterozoic sedimentary basins are an important record of crust generation processes and consequently a fundamental key to unravelling Earth's evolution through geological time. Sediments within the basins are typically deformed and metamorphosed by subsequent tectonothermal events, which can obliterate their links to source terranes. Nd-whol...

An Early Cambrian pluton, known as the Guasayan pluton, has been identified in the central area of Sierra de Guasayan, northwestern Argentina. A U-Pb zircon Concordia age of 533±4 Ma was obtained by LA-MC-ICP-MS and represents the first report of robustly dated Early Cambrian magmatism for the northwestern Sierras Pampeanas. The pluton was emplaced...

High-pressure granulites are formed within the lowermost continental crust. If exhumation is driven only by erosion, these granulites will remain at their site of formation indefinitely. Their exposure, then, requires a complex process. In this study, the Andrelândia Nappe System is used to investigate the formation and exhumation of high-pressure...
