Coarse aeolianites: sand sheets and zibar–interzibar facies from the Mesoproterozoic Cuddapah Basin, India

Sedimentary cycles in a Mesoproterozoic aeolian erg-margin succession: Mangabeira Formation, Espinhaço Supergroup, Brazil

“…Although several aeolian erg successions of Proterozoic age have been described previously (see Rodríguez-López, 2014 and references therein), and some have been the subject of facies analysis for the purpose of reconstruction of palaeoenvironment (Deynoux et al, 1989;Chakraborty, 1991;Simpson and Eriksson, 1993;Biswas, 2005;Basu et al, 2014), the aeolian succession of the Mangabeira…”

Facies architecture and heterogeneity of the fluvial–aeolian reservoirs of the Sergi formation (Upper Jurassic), Recôncavo Basin, NE Brazil

“…Herries, 1993;Mountney and Thompson, 2002;Mountney and Russel, 2009;Ulicny, 2004); and (ii) aeolian sand sheets, formed as consequence of limited wind energy or sand availability precluding aeolian dune formation (e.g. Trewin, 1993;Veiga et al, 2002;Biswas, 2005). The aeolian horizontal strata of the Sergi Formation make up to 2 m-thick packages but are not associated with intercalated high-angle cross-bedded aeolian dune deposits.…”

“…The aeolian horizontal strata of the Sergi Formation make up to 2 m-thick packages but are not associated with intercalated high-angle cross-bedded aeolian dune deposits. Therefore, it is unlikely that they represent interdune deposits, and the aeolian sand sheet hypothesis is favored in this case (Clemmensen and Abrahamsen, 1983;Clemmensen and Dam, 1993;Herries, 1993;Veiga et al, 2002;Biswas, 2005;Scherer and Lavina, 2005;Dias and Scherer, 2008).…”

Cross-bedding set thickness and stratigraphic architecture of aeolian systems: An example from the Upper Permian Pirambóia Formation (Paraná Basin), southern Brazil

“…Alternation between wind ripple strata and adhesion structures represent humidity changes of the ground, hence water table oscillations (Chakraborty and Chaudhuri, 1993;Tirsgaard and Øxnevad, 1998). Prevailing horizontal strata composed of wind-ripple lamination and adhesion structures, making up a several metres thick package distributed over a large area, suggest that these deposits represent aeolian sand sheets (Clemmensen and Abrahamsen, 1983;Clemmensen and Dam, 1993;Tirsgaard and Øxnevad, 1998;Irmen and Vondra, 2000;Biswas, 2005). Cross-bedded sets interlayered with the subhorizontal strata are interpreted as residual deposits of aeolian dunes.…”
