<title>Abstract</title> This study presents the oldest microdiamond and highly ordered graphite inclusions in garnet from Mn-rich metamorphic rocks of Borborema Province, NE Brazil, providing strong evidence for Paleoproterozoic ultra-high-pressure metamorphism (UHPM). The biogenic origin suggests that organic matter was subducted to depths exceeding 3.7 GPa temperatures above 900°C. Raman spectroscopy isotopic modeling reveal a transition disordered (~ 300–400°C) 850°C) microdiamonds,...
Introdução. Apesar da grande urbanização, o município de Campinas preserva uma interessante diversidade litoestrutural que compreende rochas sedimentares, vulcânicas, plutônicas e metamórficas médio alto grau.

Major- and trace-element U–Pb analyses of detrital zircons were performed on metavolcano sedimentary sequences igneous rocks from the Ceará Central Domain (CCD) in Borborema Province northeastern Brazil. No significant geochemical differences found between these rocks, which possibly initially deposited as parts a very large metavolcano-sedimentary sequence. Weathering source area was moderate, sediments both sands clays. The sources likely mixtures felsic intermediate predominantly an...
Abstract In the northern region of Borborema Province, a 30 km‐long mafic/ultramafic belt high pressure (HP) rocks called Forquilha Eclogite Zone has been recently discovered in Central Domain Ceará State. The comprises three groups rocks: (1) garnet amphibolites, (2) retrograded eclogites and (3) clinopyroxene–garnet all them being hosted ± kyanite + sillimanite schists orthogneisses which are often migmatized. geochemical analyses representative samples confirm differences among that were...
The Tamboril-Santa Quitéria Complex (TSQC) is one of the largest Neoproterozoic plutonic manifestations in north Borborema Province (NE Brazil). It represents an anatectic/igneous association characterized by a number magmatic pulses that occurred 650-610 Ma interval. In this paper, we present U-Pb (LA-MC-ICP-MS) zircon ages and Nd isotopes for quartz monzonites diorites southern part TSQC. belong to hybrid granitoid association, including monzonites, syenites syenites, all with abundant...
The Ceará Central Domain, in the northern Borborema Province/NE Brazil, encompasses important geological records (geosites) which allow understanding a relevant period of Earth's evolution, mainly associated to Neoproterozoic Brazilian/Pan-African Cycle and West Gondwana amalgamation, besides Neoarchean Ordovician records. presented geoheritage inventory aims characterise geosites with scientific relevance Domain. By applying method for large areas, final selection resulted eight frameworks...
A partir de mapeamento geológico em escala detalhe, 1:10.000, e estudo petrográfico sistemático foram caracterizados o modo ocorrência, a distribuição as associações minerais do retroeclogito Forquilha, que situa-se uma faixa N-S ao longo mais 16 km na região NW da Província Borborema.Tais rochas ocorrem como boudins gnaisses orto-e paraderivados e, raramente, associados cálciosilicáticas.Esta associação compõe Faixa Eclogítica estruturalmente está contato tectônico empurrão com metapelitos...
The Paulistana and Santa Filomena Complexes are situated in the southern part of Borborema Province (northeastern Brazil), Riacho do Pontal Orogen, represent meta-volcano-sedimentary sequences. We present compositional variations metasedimentary rocks new U–Pb detrital zircon data. Major trace elements indicate that from composed mostly immature to mature sediments derived felsic-intermediate sources with moderate slightly high chemical weathering. geochemical signatures sediment protoliths...
