The absence of absolute dating in glacial deposits the Paraná Basin prevents better understanding complete history Late Palaeozoic Ice Age Western Gondwana and climatic change that took place late Carboniferous. In this study, new U–Pb radiometric ages date topmost Itararé Group at 307.7 ± 3.1 Ma (Kasimovian−Moscovian) base post-glacial Rio Bonito Formation 298.8 1.9 (Ghzelian−Asselian). Correlation with other southwestern basins shows end is asynchronous. Supplementary material: Laser...
ABSTRACT Mixed‐energy coastal systems produce complex depositional records that can obscure the predominant processes controlling sediment deposition. This occurs mainly when interpretation of primary sedimentary structures is non‐unique. The Rio Bonito Formation succession infilling Capané palaeovalley in southern Paraná Basin exhibits influence tides and waves, which tidal deposits are predominant. However, environment has not been completely elucidated, little known about significance...
The study of organic matter in sediments is crucial for advancing energy resource exploration and understanding geological biogeochemical processes. This focuses on the Amazon Cone (Brazil), a region significant interest following last decade's discovery gas hydrates Brazilian waters. Methane, main released by dissociating hydrates, potent greenhouse with biogenic or thermogenic origins. Therefore, its pathways sedimentary environments fundamental climate sciences. Building data from 2023...
Zircon U-Pb geochronology was applied to investigate the provenance, depositional ages, and paleogeography of southwestern Gondwana in detrital ash fall sediments from Carboniferous Jurassic succession southern Paraná Basin. Four age populations suggest provenance local distal sources located south, southeast, southwest: (i) Archean Paleoproterozoic zircons Rio de La Plata Craton, Nico Peres Taquarembó terranes; (ii) Grenvillian basement Gondwanides Namaqua–Natal belts; (iii) Neoproterozoic...
Abstract Orbital cycles are related to variations of Earth's orbit through time and exert profound control on glacial interglacial climates due changes in insolation. In this study, we aim test whether orbital millennial‐scale climate conditioned the deposition rhythmites southern Gondwana during Late Paleozoic Ice Age (LPIA). We present first cyclostratigraphic study based X‐ray fluorescence records from a 27‐m‐thick interval LPIA southeastern border Paraná Basin, Brazil. TiO 2 Fe O 3...
ABSTRACT Fine-grained rhythmites are a recurrent sedimentary facies in glacially influenced marine and lacustrine sequences throughout geological time. Paleoenvironmental interpretation of these ancient deposits has been challenge, because similar may have formed different depositional contexts. In the Paraná Basin, Itararé Group contains numerous successions fine-grained rhythmites, deposited Carboniferous during Late Paleozoic Ice Age (LPIA). The described characterized by intercalation...
Abstract. Minerals are the fundamental record of abiotic processes over time, while biominerals one most common records life due to their easy preservation and abundance. However, distinguishing between minerals is challenging superimposition repetition geologic interference ubiquitous diverse on Earth's surface crust. Mineral dubiofossils, being potential outcomes both biotic environments, emerge as valuable entities that can contribute significantly understanding this issue, facilitating...
In this study we present a mobile application for geoscience. It refers to digital field book automating data collection and outcrop/core description, optimizing the final processing. Sensors were developed semi-automatic collection, real time calculations, measurements of dip angles directions, geographic location, among others. Field tests performed comparing traditional method with proposed method. The preliminary results show good acceptance by geoscientists an improvement in required...
Abstract. Bituminous shales are associated to worldwide geological events, such as mass extinction, anoxia and climatic changes, mainly when preserved in carbonate ramps, constitute reliable records of this dynamics. However, a minority data still exist that measure the Permian, especially Southern Hemisphere Panthalassic Ocean compared numerous studies Oceanic Anoxic Events Cretaceous or Tethys. The Late Permian extinction was most severe past 500 million years, which wiped out over 90 %...
<p>The Late Paleozoic Ice Age (LPIA), one of the best known and prolonged glaciation events in Earth's history, resulted deposition glacial sediments over Gondwana. The terminal deglaciation, a diachronic event starting earlier at western later eastern part continent, caused sea level rise widespread transgressive sedimentary successions. Paraná Basin is these basins recording both influenced (Itararé Group) post-glacial (Guatá deposits....
