This study presents field and chronological investigations along the coast of northeastern Brazil from ~4°S to 9°S latitude, which corresponds ~700 km coastline under a semi-diurnal mesotidal regime. We investigated wave-built terrace deposits dated sediments using optically stimulated luminescence thermoluminescence methods on quartz grains. The terraces yielded two main age groups: 200-230 ka 100-130 ka, we interpreted as depositional ages. correlated these groups with oxygen-isotope...
This study deals with the Holocene relative sea level (RSL) changes along Brazilian northeastern coast, in particular states of Pernambuco and Paraíba. It presents 25 superficial indicators, dominantly a biological nature (i.e., vermetid gastropod tubes encrusted on rocky surfaces, as well mollusk shells live positions contained within beachrocks paleomangrove deposits). Moreover, diatomological palynological analyses have been carried out drilling core obtained from Olhos d'Água lagoon...
We present two pollen diagrams from the semi-arid Caatinga of Catimbau National Park, in Pernambuco and a Mauritia palm forest Caatinga/Cerrado ecotone southern Piauí, NE Brazil, spanning last 10,000 cal. yrs BP 1,750 cal BP, respectively. These records contain signature local vegetation permit correlation signal with regional climatic changes. The record shows Zizyphus sp., typical taxon, all three zones indicating predominance arboreal taxa adapted to high humidity ca. 6,000 gradual...
The objectives of this study were the biostratigraphic and paleobiogeographic interpretations calcareous nannofossil records Romualdo Formation (Aptian-Albian) in south-central portion Araripe Basin. methods used to process samples decanting, smear slide, centrifugation, ultra-thin section confection. taxonomic carried out through qualitative quantitative investigations. A total 11 genera 17 species nannofossils, namely, Biscutum constans, sp., Braarudosphaera africana, Calculites...
Os mamiferos fosseis de Fazenda Nova, na regiao Nordeste do Brasil, sao representativos um intervalo mais antigo que a transicao Pleistoceno- Holoceno. Incluem Xenarthra, Glyptodontidae, Glyptatelinae (representado por Pachyarmatherium sp.), Glyptodontinae, Glyptotheriini, Hoplophorinae gen. et sp. indet., Pampatheriidae Holmesina cf. H . paulacoutoi ), Megalonychidae Megatheriidae ( Eremotherium laurillardi Notoungulata, Toxodontinae Toxodon sp.) e Proboscidea (cuja forma conhecida...
A systematic study is made of Early Cretaceous (late Aptian/earlyAlbian) ostracod assemblages from the Santo Antnio section. This section characterized by sediment belonging to post-rift sedimentary sequence Romualdo Formation in southern-central region Araripe Basin, Brazil and represents on first marine ingression interior continent, during beginning formation Atlantic Ocean. The Antonio presents ostracods greater diversity than previously known. Nineteen samples were analyzed, yielding a...
This study presents the regional geological-geomorphological map of Quaternary coastal record Rio Grande do Norte State, Brazil, with emphasis on aeolian deposits. The comprises aeolian, alluvial, and marine deposits (peat, intertidal, tidal flat deposits). They were dated by thermoluminescence (TL) 14C methods. One active three inactive geomorphological domains have been identified, which formed since early accumulation sands from plain such continental sources as Barreiras Formation. TL...
The Romualdo Formation, Araripe Basin, crops out in the municipality of Exu, Pernambuco State, exposing coquinas. Fauna survey, taphonomic analysis macrobenthos, and identification sedimentary facies outcrop were carried to contribute paleoenvironmental understanding Formation. association molluscs (Cerithium sp., Tylostoma ranchariensis, Aguileria dissita, Brachidontes araripensis unidentified cassiopids) echinoids species Bothryopneustes suggests sedimentation marine environment....
A Formação Romualdo contém assembleias fósseis de invertebrados compostas principalmente moluscos gastrópodos e biválvios, equinoides, táxons importantes indicativos influência marinha durante o Aptiano-Albiano da Bacia do Araripe, no nordeste Brasil. Este trabalho descreve ilustra formalmente biválvios Romualdo, pontuando as características paleoecológicas dos gêneros com base em 750 espécimes estados Pernambuco, Ceará Piauí. Esta análise resultou na identificação Cerithium sergipensis...
Este trabalho descreve um osso isolado de pterossauro da Formação Romualdo (Aptiano / Albiano) coletado em novo sitío fossilífero na porção sudeste Bacia do Araripe. O espécime (DGEO-CTG-UFPE 7516) consiste uma ulna preservada três dimensões que apresenta semelhanças morfológicas com os Pteranodontoidea e é tentativamente referido a Anhangueridae por causa presença crista ventral bem desenvolvida extremidade distal. As características histológicas sugerem era indivíduo ontogeneticamente...
Absolute datings by luminescence of crystals are successfully used in Quaternary deposits many researchers different countries. Nevertheless, these methods still few times Brazil and even unbelieved some research groups. The dating based theory interaction ionizing radiations with the matter, age sample to be dated is calculated from concentration defects induced matter. For first time, incident cosmic radiation data measured presented, which important determinations made methods....
