Petrology of the Namib Sand Sea: Long-distance transport and compositional variability in the wind-displaced Orange Delta

The fan-like forms in the southern margin of the Mazovian Lowland area (Central Poland): a new high-resolution textural-timing study

“…Three groups were distinguished: quartz (Q), feldspars (F) and other crystalline rocks (CR). Of particular concern were platy micaceous minerals, whose enrichment might support the influence of granitic sources and/or short aeolian transportation (Kasper-Zubillaga and Zolezzi-Ruiz 2007; Garzanti et al 2012). …”

“…The sedimentary setting thus seems to be transformed by the winnowing out of both slow-settling micas (Garzanti et al 2012), and easily weathered feldspars (Galović et al 2011). Furthermore, the presence of either mica or feldspars grains precludes an aeolian depositional environment (Swezey 1998).…”

Owens Lake dune fields: Composition, sources of sand, and transport pathways

“…The dynamics of these systems are controlled by the supply of sand-sized sediment, the availability of this sediment for transport by the wind, and the transport capacity of the wind (Kocurek and Lancaster, 1999). Identifying and characterizing the components of such systems can be challenging, but analysis of the mineral and chemical composition of aeolian sands, as well as those from potential fluvial, alluvial, or lacustrine sources can provide valuable information on sand sources and transport pathways, as demonstrated for dune fields on the Great Plains (Muhs et al, 1996), the Mojave and Sonoran Deserts (Muhs et al, 2003;Scheidt et al, 2011), as well as Namibia and the Arabian Peninsula (Garzanti et al, 2012(Garzanti et al, , 2013. The results of such analyses can also be used to constrain the conditions in which dune construction occurred (e.g.…”

Heavy-mineral derived provenance study of Quaternary sediments of the Mazovian Lowland, Central Poland

“…Sedimentary processes re-shape the initial composition of HM assemblages (Garzanti et al 2012;Morton, Hallsworth 1999), in a way that they should differ from their source rock (Sevastjanova et al 2012). Following such assumption, the most liable to dissolution are i.e.…”

“…The HM can be found in dune flanks due to wind turbulences (Garzanti et al 2012) and stoss side of dune, where flow velocity increases (Komar 2007). Authors found dense minerals in dune flank at the Międzyborów site, but also in the sediments of the coversand, where garnets, zircon, tourmaline, disten and staurolite prevail (Table 1; Figs 3, 4A-B).…”
