ICE-KEEL SCOUR MARKS IN THE GEOLOGICAL RECORD: EVIDENCE FROM CARBONIFEROUS SOFT-SEDIMENT STRIATED SURFACES IN THE PARANA BASIN, SOUTHERN BRAZIL
(Journal Of Sedimentary Research, 2014-01-01) [Artigo]
Soft-sediment glacially striated surfaces are common structures in ancient glacial successions, such as the Gondwanic Paleozoic record, and document ice erosion on non lithified beds. In most cases, they have been interpreted ...
The 2009 earthquake, magnitude m(b) 4.8, in the Pantanal Wetlands, west-central Brazil
(Anais Da Academia Brasileira De Ciencias, 2016-09-01) [Artigo]
The main goal of this paper is to characterize the Coxim earthquake occurred in June 15th, 2009 in the Pantanal Basin and to discuss the relationship between its faulting mechanism with the Transbrasiliano Lineament. The ...
Analysis of a Cretaceous (late Aptian) high-stress ecosystem: The Romualdo Formation of the Araripe Basin, northeastern Brazil
(Cretaceous Research, 2019-03-01) [Artigo]
The Cretaceous (upper Aptian) Romualdo Formation of the Araripe Basin, northeastern Brazil, is a marine-influenced, predominantly fine-grained siliciclastic unit. In the eastern part of the basin, it corresponds to a ...
Limnogeology in Brazil's "forgotten wilderness": a synthesis from the large floodplain lakes of the Pantanal
(Journal of Paleolimnology, 2011-08-01) [Artigo]
Sediment records from floodplain lakes have a large and commonly untapped potential for inferring wetland response to global change. The Brazilian Pantanal is a vast, seasonally inundated savanna floodplain system controlled ...
Lacustrine records of Holocene flood pulse dynamics in the Upper Paraguay River watershed (Pantanal wetlands, Brazil)
(Quaternary Research, 2012-09-01) [Artigo]
The Pantanal is the world's largest tropical wetland and a biodiversity hotspot, yet its response to Quaternary environmental change is unclear. To address this problem, sediment cores from shallow lakes connected to the ...
Glacially striated, soft sediment surfaces on late Paleozoic tillite at São Luiz do Purunã, PR
(Anais da Academia Brasileira de Ciências, 2005-06-01) [Artigo]
Estrias e sulcos encontrados sobre três camadas decimétricas, estratigraficamente superpostas, de tilito de alojamento neopaleozóico do Subgrupo Itararé, na porção norte da Bacia do Paraná, foram formados por aração de ...
