Origin of red beds and paleosols in the Palaeoproterozoic Transvaal and Olifansthoek Supergroups of South Africa: provenance versus metasomatic controls
(Wiley-Blackwell, 2018-01-01)
The Palaeoproterozoic Transvaal and Olifantshoek Supergroups of South Africa contain some of the earliest hematite-rich sedimentary rocks (red-beds) and paleosols on record. The origin of these rocks has been variously ...
Geological setting and paleomagnetism of the Eocene red beds of Laguna Brava Formation (Quebrada Santo Domingo, northwestern Argentina)
(Elsevier Science, 2013-01)
The red bed succession cropping out in the Quebrada Santo Domingo in northwestern Argentina had been for long considered as Upper Triassic-Lower Jurassic in age based on weak radiometric and paleontological evidence. ...

(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2019-02-18)
Polyurethane foams (PU) may be used as the immobilization matrix for chitosan, in order to overcome/minimize the disadvantages with respect to chitosan as an adsorbent. However, the polyurethane and chitosan foams synthesized ...
Paleomagnetism of the Carboniferous-Permian Patquía formation, Paganzo Basin, Argentina: Implications for the apparent polar wander path for South America and Gondwana during the late Palaeozoic
(Universidad de Barcelona, 2010-12)
The magnetic properties of the Carboniferous-Permian red beds of the Patquía Formation at Punta del Viento, Sierra de Umango and some previously reported localities, all in the Paganzo Basin (Argentina) have been studied. ...
Large-Scale Bleaching of Red Beds Related To Upward Migration of Hydrocarbons: Los Chihuidos High, Neuquén Basin, Argentina
(Society for Sedimentary Geology, 2014-05)
The striking arrangement of colorful facies in the sandstones outcrops of the Los Chihuidos high, Argentina, has been attributed to the surface expression of hydrocarbon-induced alteration. The Huincul Formation (late ...
