“…3A). The laminae are 2 -12 mm thick with grain-size segregation and sometimes characterized by inverse grading; they are similar to the "pin stripe lamination" described by Fryberger and Schenk (1988) (Fig. 3B).…”

“…This sedimentary structure is produced by migration of climbing wind ripples. The similarity with the "pin stripe lamination" of Fryberger and Schenk (1988), the grain-size segregation (Eriksson & Simpson 1998) and the presence of high rounded sandstone clasts, typical of wind transport (Mahaney 2002), suggest this interpretation. Also the architectural framework, in which the laminated sandstone sets are separated by inclined (< 15°) bounding surfaces (truncation surfaces), supports this interpretation ).…”

Some present-day eolian sand sheets have small and width dunes, called zibars, as common type of depositional morphology. Their formation is related to different stabilizing factors, which reduce the availability of clastic materials for eolian processes. In fact, zibars are dunes which do not have time to develop a larger dune with slipface (proto-dune). Dunes in sands sheet areas generally are constructed by wind ripple laminations and commonly generate sedimentary succession less than 20 m thick, which are the consequence of low sand supply. This study deals with an uncommon eolian sand sheet sedimentary succession more than 50 m thick, Proterozoic in age, known as Bandeirinha Formation. This paper tries to explain the anomalous thick of this sand sheet sedimentary succession. High thickness was probably the result of a high input of sand material, combine with low availability of sand, thus allowing the only construction of proto-dunes (zibars). Early cementation, due to near-surface evaporation of saline water, has been proposed as main factor that reduced the sand availability into this eolian system. Finally, the subsidence processes related to the first stage of rift Espinhaço Basin must have generated the accommodation space to preserve the sand sheet succession.

RESUMO: Em alguns lençóis de areia eólica atuais existem dunas pequenas e largas, chamadas zibars, como tipo comum de morfologia deposicional. Sua formação é relacionada a diferentes fatores de estabilização, os quais reduzem a disponibilidade de materiais clásticos para os processos eólicos. De fato, os zibars são dunas que não tiveram tempo para se desenvolver como grandes dunas (protodunas). As dunas dos lençóis de areia (zibars) geralmente são construídas por laminações de marcas onduladas de vento e comumente geram sucessões com menos de 20 m de espessura

“…2b), most the sedimentary sequence between depths of 1 0.5 m and 3.1 m is interpreted as outwash, because it is dominated by pebbly sand with clasts as big as 23 cm in diameter and has a layer of sandy gravel at the base. Within this outwash are sand$sheet deposits (2.30-2.55 m depth) whose horizontal laminae are inversely graded (pin$stripe lamination of Fryberger and Schenk, 1988) and attributed to migrating wind ripples. At Crumbling Point, on northern Summer Island, a sand sheet infills a channel$shaped depression interpreted as a meltwater channel of the LIS (Murton 1 1997).…”

Aeolian periglacial sand deposits are common in the Tuktoyaktuk Coastlands of Western Arctic Canada. Regionally extensive and thick aeolian sand$sheet deposits have been observed in two major stratigraphic settings: within a sand unit characterized by large aeolian dune deposits; and interbedded with glaciofluvial outwash from the Laurentide Ice Sheet (LIS). Small, localized sand sheets have also been observed along the tops of sandy bluffs, within sequences of drained thermokarst lakes deposits and as an involuted veneer above buried basal ice of the LIS.On the basis of radiocarbon and optically stimulated luminescence (OSL) dates from preserved periglacial aeolian sand sheets and dunes a regional chronostratigraphy is presented which indicates that both extensive dunes and sand sheets accumulated mainly between . 30 and 13 ka. A switch to dominantly sand$sheet aggradation at c. 14-13 ka, with sand sheets forming widely until . 8 ka, is attributed to (a) surface armouring by glacial deposits associated with the advance of the LIS; and (b) amelioration of the climate from cold aridity. An absence of OSL dates between . 8 and 1 ka suggests that sand sheets stabilized during much of the Holocene. Local sand$sheet aggradation during recent centuries has occurred near sandy bluffs and on the floors of drained thermokarst lakes. The OSL dates constrain the maximum extent of the LIS in the Tuktoyaktuk Coastlands to Marine Isotope Stage 2.

“…The thickest sets are found far from the Encantadas Fault Zone, while towards the basin border the sets become smaller, rarely reaching one meter. Pin-stripe lamination (Hunter 1977, Fryberger andSchenk 1988) is conspicuous (Fig. 2d).…”

This work presents a study of selected outcrops from the Pedra das Torrinhas Formation of the Guaritas Group (Cambrian, Camaquã Basin), near the basin bordering Encantadas Fault Zone. The studied succession includes alluvial fan deposits that pass laterally into eolian deposits. Sedimentary facies and architectural element analysis were performed, followed by sedimentary petrography and microscopic porosity analysis, aiming to characterize the porosity of the deposits and its spatial distribution. The main objective was to contribute to a better understanding of the porosity spatial distribution in depositional systems characterized by the interaction between alluvial and eolian processes, with special reference to deposits formed prior to the development of terrestrial plants. Porosity values are related to depositional processes, with higher porosities associated to eolian dune deposits (mean of 8.4%), and lower porosity related to interdunes (mean of 3.4%) and alluvial fans (mean of 4.3%). Architectural elements analysis revealed the spatial relationships of these deposits, a response to the interplay of the eolian and alluvial processes. The integration of porosity data reveals that the interaction of alluvial and eolian processes results in heterogeneous distribution of porosity at the facies association scale. Eolian reworking of alluvial facies increases porosity whereas sheet-flood and other alluvial processes in the interdune areas reduce porosity.
