“…Samples exhibiting a predominance of authigenic material were eliminated from analysis. Furthermore, both visual inspection and previous studies on these strata indicate no to minimal instances of quartz overgrowths (Shelley et al 2019;Price et al 2020;Milad et al 2020;Duarte et al 2021;Supplemental Files 3, 4), lending further confidence to the fidelity of subsequent particle-size analyses. Particle sizes of fully disaggregated samples were measured using a Malvern Mastersizer 3000 Laser Particle Size Analyzer (LPSA).…”

“…In contrast to the prevalence of fluvio-deltaic inferences for the study units, few have mentioned eolian processes (e.g., Miller and Cullen 2018;Shelley et al 2019), whilst others make a connection to the origin of chert in correlative units such as the Arkansas Novaculite, the Caballos Novaculite, and cherts of the Osage-Meramecian strata (Banks 1970;Lowe 1976;Cecil 2004Cecil , 2018b. Schieber (2016) explicitly dismissed an eolian origin for these mudrocks based on the presumed need for large erg systems to supply the fines via saltation abrasion of sand; yet eolian abrasion produces very little silt (Swet et al 2019(Swet et al , 2020Adams and Soreghan 2020).…”

Upper Devonian and Lower–Middle Mississippian strata of the North American midcontinent are ubiquitously fine-grained and silt-rich, comprising both so-called shale as well as argillaceous limestone (or calcareous siltstone) that accumulated in the Laurentian epeiric sea. Although long recognized as recording marine deposition, the origin and transport of the fine-grained siliciclastic material in these units remains enigmatic because they do not connect to any proximal deltaic feeder systems. Here, we present new data on grain size, whole-rock geochemistry, mineralogy, and U-Pb detrital-zircon geochronology from units across Oklahoma; we then integrate these data with models of surface wind circulation, refined paleogeographic reconstructions, and correlations from the greater midcontinent to test the hypothesis that wind transported the siliciclastic fraction to the marine system. The exclusively very fine silt to very fine sand grain size, clear detrital origin, widespread distribution over large regions of the epeiric sea, Appalachian sources, and paleogeographic setting in the subtropical arid belt far-removed from contemporaneous deltaic feeder systems are most consistent with eolian transport of dust lofted from subaerial delta plains of the greater Appalachian orogen and incorporated into subaqueous depositional systems. Delivery of dust that was minimally chemically weathered to Devono-Mississippian epeiric seas likely provided essential nutrients that stimulated organic productivity in these commonly organic-rich units.
