“…Resende basin is interpreted as formed in an extensional regime as consequence of platform reactivation (Heilbron et al, 2020, Ramos et al, 2005. The results here reported is particularly useful in constrain the timing of initial crustal extension in the Soutwestern Brazil, as result of regional uplift and basin formation.…”

The Resende Basin (Eocene-Oligocene) is a continental taphrogenic structure associated with the Continental Rift of Southeast Brazil and includes the Itatiaia and Acácias members. While the sediment provenance of the Itatiaia member is known, such knowledge regarding the Acácias Member is lacking. This work studies U-Pb ages and Lu-Hf data analyzed by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) in detrital zircons to investigate the sandstone provenance of the Acácias Member. The results suggest that Acácias Member rocks are composed predominantly of Neoproterozoic sources (60%), significant Paleoproterozoic sources (34%) and smaller contributions from Mesoproterozoic (4%) and Archean (2%) sources. The orthogneisses of the Juiz de Fora and Quirino complexes and the metasedimentary rocks of the Andrelandia Complex and Paraíba do Sul were probably the source rocks of Archean and Paleoproterozoic materials. The metasedimentary Embú Complex may be the source of Mesoproterozoic sediments, and the granitoid bodies located south of the Resende Basin (namely,the Rio Turvo granitoid) were important Neoproterozoic sources. No Late Cretaceous ages were found in the 301 analyzed zircons, suggesting that the extensional process that originated in the basin occurred before the Itatiaia alkaline intrusions. In addition, other causes for the lack of zircon grains with the age of alkaline intrusive rocks (Morro Redondo ≈72-70 Ma; Itatiaia ≈70 Ma) may have been related to the basin location with a structural high that could have prevented the alkaline detritus from the Itatiaia and Morro Redondo intrusive bodies from reaching the study area and restricted the supply of sediments from a fluvial system with tributaries on the northern edge. In conclusion, the results of this work reveal that U-Pb ages in detrital zircons reveal a tectonic-driven of the Resende basin sediments. In this way, interpretations of tectonic environments that affected sedimentation require a thorough understanding of the lithological units that compose the basin stratigraphy and factors such as the directions of currents and the presence of structures that compartmentalized sedimentary processes.

“…Based on the study of metabasic and metapelitic rocks of the São Fidélis Group (Costeiro Domain, Oriental Terrane), Santos et al (2005) determined a P-T metamorphic history with peak conditions ranging in the interval of 750 -800 ° C and 8-9 kbar. They have interpreted it as an early M 1 event, possibly equivalent to the M 0 event of Duarte et al (2012) (Heilbron et al, 2020), which obtained significantly lower values for both temperature and pressure (600-700 °C and 5 to 6.5 kbar).…”

“…This orogen comprises four tectonostratigraphic terranes imbricated from SSE to NWW toward the São Francisco Craton (Heilbron et al, 2004): Occidental Terrane, Central Superterrane (now inclunding Cambuci Domain, Paraiba do Sul and Embu terranes - Heilbron et al, 2020) Oriental Terrane and Cabo Frio Terrane; the last one amalgamated at 520 Ma. The study area is located in the contact between the Central Superterrane and Oriental Terrane and includes the following domains which is structured, from bottom to top as: a) the Cambuci Domain of the Central Superterrane; b) the Costeiro Domain, which includes the Rio Negro Magmatic Arc -790-610 Ma (Tupinambá et al, 1998); and c) the Italva Domain with the Serra da Prata Arc (ca.…”

Neoproterozoic-Cambrian rocks from the Oriental Terrane and the Central Superterrane of the Ribeira Belt occur in northwest of Rio de Janeiro state. This paper presents new data on field research, petrology, mineral chemistry and conventional geothermobarometry, fundamental to understanding the geology of the region. The metabasic rocks from the Cambuci Domain are associated with the Central Superterrane retroarc basin and record two metamorphic events: M 0 (before the formation of the main foliation, under conditions of 788 °C) and M 1 (contemporary to the main foliation, with peak at 718-752 ºC and 6.62 kbar). The rocks from the Costeiro Domain, interpreted as the Rio Doce arc (Angelim Suite) and the retroarc basin (São Fidélis Goup) of the Oriental Terrane record a metamorphic peak at granulite facies yielding the highest pressure and temperature among the studied domains (752-784 °C and 8.2-9 kbar). The Italva Domain amphibolites represents the retroarc basin of the Oriental Terrane. Temperature and pressure values obtained for the Italva Domain metamorphic peak record 731 ºC and 6.78 kbar, respectively, in the transition zone between upper amphibolite and granulite facies conditions. This work presents the newest record of metamorphic evolution for the Oriental Terrane of the Ribeira Belt, suggesting an anticlockwise P-T-t path and near-isobaric cooling (IBC) for the rocks of the Cambuci Domain. Therefore, these results contribute to the understanding of the evolution of orogenic belts during the amalgamation of the Gondwana in the Neoproterozoic.

“…This process that involved subduction, collision, and the collapse of the orogen, between 790 Ma and 480 Ma (Tupinambá et al, 2012;Heilbron et al, 2016;Schmitt et al, 2018), is considered one of the most comprehensive examples of the Precambrian diachronic orogenic history (Heilbron et al, 2020). During these continental colli- sion events, migmatites, ortho and paragneisses, and granitic rocks were formed, including those that are found in the coastal area of Rio de Janeiro.…”

A heritage stone of Rio de Janeiro (Brazil): the Facoidal gneiss

et al. 2021

View full text Add to dashboard Cite

This paper presents the Facoidal gneiss, the most significant and characteristic natural and heritage stone of Rio de Janeiro, Brazil, also known as 'the most carioca of rocks. ' The metropolis that is a World Heritage Cultural Landscape was built on, over, around, and with local stones, mostly Neoproterozoic gneisses. Among them, Facoidal gneiss occurs both sides of the Guanabara Bay, shaping its natural monuments as the Corcovado and the Sugar Loaf. It is composed of K-feldspar megacrysts usually deformed, looking like eyes (augen), arranged in a quartzfeldspar and biotite rich matrix. Its colour varies from pink to greyish. This stone was substantially used as a building material in many heritage monuments and buildings, in frames of windows and doors in houses, in sidewalks and public infrastructures. The aggressive environment of Rio de Janeiro, a tropical coastal megalopolis, is reflected in decay patterns such as loss of matrix and spalling. There are no quarries in production as this rock outcrops stand inside nature conservation or urbanized areas. The current impossibility of extracting replacement material justifies calling attention to this stone for the better conservation of Rio de Janeiro's built heritage.
