A classification scheme for sedimentary architectures arising from aeolian-fluvial system interactions: Permian examples from southeast Utah, USA

The Late Paleozoic Ice Age in western equatorial Pangea: Context for complex interactions among aeolian, alluvial, and shoreface sedimentary environments during the Late Pennsylvanian – early Permian

“…The Undivided Cutler Gp deposits are interpreted as alluvial fans, debris flows and proximal braided-stream deposits (Campbell, 1980;Mack & Rasmussen, 1984;Schultz, 1984;Dubiel et al, 1996) with occurrence of aeolian deposits (Hême de Lacotte & Mountney, 2022). Sedimentation was influenced by contemporaneous growth of anticlinal structures, such as the Cane Creek anticline (Wengerd & Matheny, 1958) caused by movements of the deep Paradox Salt Fm (Venus et al, 2015).…”

“…outcrop) and considered fluvial-aeolian or sabkha-aeolian-fluvial interaction (e.g. Targaart et al, 2010;Mountney, 2012;Pettigrew et al, 2021;Hême de Lacotte & Mountney, 2022).…”

“…The upper part of their studied series, with well-developed aeolian facies could correspond to the White Rim Fm. Moreover, Hême de Lacotte and Mountney (2022) proposed a model of architectural relationships for these fluvial-aeolian deposits.…”

“…Several models propose either an interaction between aeolian, fluvial and lacustrine (e.g. Clemmensen et al, 1989;Tirsgaard & Oxnevad, 1998;Sweet, 1999;Mountney & Jagger, 2004;Bourquin et al, 2009;Hême de Lacotte & Mountney, 2022), or aeolian and marine environments (Blanchard et al, 2016). Some models discuss the interaction between all three, aeolian, marine and fluvial deposits (e.g.…”
