Grupo itararé (P - C da bacia do Paraná) nas regiões de Limeira e Piracicaba - SP: Contribuição ao estudo das litofácies
(2009-12-01)
The Permian-Carboniferous Itararé Group is one complexe lithostratigraphic unit of the Paraná Basin, southeastern Brazil, typically marked by discontinuity of its lithofacies. Under the exploratory point of view, the unit ...
The use of piezocone tests for high-resolution stratigraphy of Quaternary Sediment Sequences in the Brazilian coast
(2007-01-01)
Correlations between mapping units of costal sedimentary basin and interpretation of piezocone test results are presented and discussed based on examples from Caravelas strandplain, (State of Bahia), Paranaguá (State of ...
Stratigraphic correlation of Holocene phonolitic explosive episodes of the Teide-Pico Viejo Complex, Tenerife
(Lyell collection, 2014-03)
Teide and Pico Viejo (TPV) are twin stratovolcanoes that form one of the largest alkaline volcanic complexes in the world. They began forming inside the caldera of Las Cañadas about 200 ka ago and are largely made up of ...
Early Cretaceous crustacean microcoprolites from Sierra de la Cara Cura, Neuquén Basin, Argentina: Taphonomy, environmental distribution, and stratigraphic correlation
(Elsevier, 2014-02)
A new Early Cretaceous association of crustacean microcoprolites from the southern Mendoza sector of the Neuquén Basin, includes Palaxius salataensis Brönnimann, Cros and Zaninetti, 1972; Palaxius caucaensis Blau, Moreno ...
Correlações Estratigráficas Conflitantes no Limite Permo-Triássico no Sul da Bacia do Paraná: O Contato Entre Duas Seqüências e Implicações na Configuração Espacial do Aqüífero GuaraniConflicting stratigraphic correlations in the Permo-Triassic boundary in south Paraná Basin: the contact between two sequences and implications on Guarani Aquifer System

Darriwilian (Middle Ordovician) δ13Ccarb chemostratigraphy in the Precordillera of Argentina: Documentation of the middle Darriwilian Isotope Carbon Excursion (MDICE) and its use for intercontinental correlation
(Elsevier Science, 2013-03)
Although documented from Estonia, Latvia, Sweden, eastern North America, and China, the Middle Ordovician (Darriwilian) positive δ13C excursion known as the MDICE has previously not been recognized with certainty in South ...
Late Miocene ignimbrites at the southern Puna-northern Sierras Pampeanas border (~27°S): Stratigraphic correlation
(Elsevier, 2015-10)
New field observations and petrographic and geochemical data of pyroclastic deposits exposed along the Las Papas valley (border between southern Puna and northern Sierras Pampeanas, Argentina) and further north, lead us ...
Stratigraphical distribution of the Ordovician conodont Erraticodon Dzik in Argentina
(Elsevier, 2013-08)
Three different species of the Ordovician genus Erraticodon Dzik are described and illustrated. E. patu Cooper is reported from the Lower-Midde Ordovician strata of the Acoite and Alto del Cóndor formations. E. cf. E. ...
Cross-stratigraphies from a seismically active mud lens off Peru indicate horizontal extensions of laminae, missing sequences, and a need for multiple cores for high resolution records
(Elsevier, 2014)
Marine laminated sediments in dysoxic areas of the ocean floor are an excellent archive for high-resolution climate reconstructions. While the existence of discontinuities produced by natural events, such as underwater ...
