Permian bivalve molluscs from the Gai-As Formation, northern Namibia: systematics, taphonomy and biostratigraphy
(Alcheringa, 2011-01-01) [Artigo]
Fossil bivalves from two horizons in the Gai-As Formation of NW Namibia are tentatively correlated with mid-Permian taxa of the Passa Dois Group of Brazil, supporting the concept that the Parana Basin extended into Africa. ...
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 ...
Upper-mantle seismic anisotropy from SKS splitting in the South American stable platform: A test of asthenospheric flow models beneath the lithosphere
(Lithosphere, 2011-04-01) [Artigo]
Upper-mantle seismic anisotropy has been extensively used to infer both present and past deformation processes at lithospheric and asthenospheric depths. Analysis of shear-wave splitting (mainly from core-refracted SKS ...
