“…For the Midwest, technical studies of dust production, transport, and deposition received large-scale federal funding after the dust bowl years (see, e.g., Chepil, 1957aChepil, , 1957bChepil and Woodruff, 1957). Results from a network of stations to monitor dust fall in the eastern United States were published by Smith et al (1970).…”

In western Illinois, many soil profiles developed into upland loess deposits (Peoria Silt) contain Archaic period artifacts greater than 3500 yr B.P. in stone zones below plow level. For artifacts in prairie and prairie-forest transition soils (not forest soils), depth distribution curves suggest they were buried in biomantles by small soil fauna. Artifacts of sizes archaeologists routinely collect generally move down while retaining fine-scale horizontal integrity. The process results in stratigraphic separation of Archaic and Woodland period components that otherwise would commingle at the surface. The characteristic distribution of known upland sites, narrowly rimming stream valley headwaters, reflects incomplete burial of materials on steeper forested slopes. On adjacent gently sloping upper shoulder segments of valleys where grassy cover more strongly influences soil development (and by inference on broad level uplands where true prairie soils occur), Archaic artifacts will be buried in the biomantle and go undetected by surface surveyors. ᭧

“…Hence, more mica in the soil or loess will result in a lower K/Rb ratio. In Figure 5.6, The K/Rb vs. Ti/Nb ratios for the soils in this study show that despite the large amount of loess deposition in the Flint Hills reported by Smith et al (1970) (50 kg/ha/mo. ), these soils are not purely loess derived.…”

The Critical Zone is the realm where rocks meet life. This study examines the physicochemical interactions that occur when interbedded limestone-shale systems and kimberlitic rocks weather to form soils. Fast weathering processes with extensive soil loss have been a major environmental concern in the Flint Hills for decades. Knowledge of soil formation processes, rates of formation and subsequent loss, and understanding how these processes differ in different systems are critical for managing soil as a resource. Kimberlites are CO2-rich igneous rocks that are high in Mg and Fe; they are compositionally distinct from the Paleozoic limestones and shales found throughout the rest of the region. This study will compare the geochemistry and mineralogy of the Stockdale Kimberlite in Riley county to that of interbedded limestone-shale system typical of the Flint Hills as sampled from Konza Prairie LTER. Bulk composition and mineralogy of the soils overlying these different bedrock types have been analyzed using X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), bulk elemental extractions, and particle size analyses. Results show that the kimberlitic soils have higher concentrations of Fe, Mg, Ca, K and some trace elements in greater proportions (e.g. Ti, Ni, Cu).The weathering products differ mineralogically as well, e.g. lizardite is abundant in kimberlitic soils and absent from the limestone terranes. Kimberlite derived soils also contain minerals as well such as kleberite (an alteration product of illminite), phlogopite, and magnetite. Kimberlite-sourced soils have different physical properties than the thin limestone-sourced soils surrounding them. Particle size analysis shows that the limestone-shale soils have different proportions of the clay size fraction in different core locations (~47% in highlands, ~51% at watershed base, ~41% in lowlands) whereas kimberlitic soils have a larger sand fraction than Konza (~19% vs. 10%). Clay minerals from the limestone-shale system reveals clay micas, kaolinite, and some expandable 2:1 layer silicates. Clay minerals from kimberlite-sourced soils are identified as primarily smectites with clay micas and kaolinites. Similarities between the kimberlite and limestone-shale soils are primarily seen in the shallower portions of the soil profile, suggesting that loess/wind-blown dust make a significant contribution to the soils in both areas. It could be concluded that kimberlite-sourced and limestone-shale-sourced soils produce weathering products that differ both chemically and mineralogically and could potentially have agricultural significance in terms of water retention as well as ionic and nutrient mobilities in these soils.iv

a De~resión de Granada (SE de la~e~~nsula Ibérica) pres~~ta, en áreas no urba~as ( no mdustnales, una tasa anual de deposlclOn de polvo atmosfenco de 23,06 g·m-2 ·ano-, obtenida a partir de observaciones semanales durante el año 1992. Este dato es el resultado de una metodología propia, que complementa los métodos de trabajo seguidos por otros investigadores. Dada la ubicación de la estación, este valor es representativo del fondo regional de partículas sólidas en suspensión. La distribución temporal de las tasas presenta importantes fluctuaciones, relacionadas con la dirección predominante del viento, que también parece tener influencia sobre los componentes del polvo.Estos datos se integran en el conocimiento de los procesos edafogenéticos de los suelos mediterráneos. ABSTRACTWe evaluated the deposition rate of atmospheric dust in a non urban area of the Granada Depression (SE of Iberian Peninsule). By using in part existing methodology, we determined arate of 23.06 g·m-2 ·yc' on the basis of weekly observations, that showed marked variations, partially controlled by Saharan winds. The components of the dust can indicate source area. Thus, southerly winds provide considerable allochthonous components from North Africa, while others are local. Despite the scarcity of industrial activity, signs of contamination were recorded. The employed methodology complements the work methods used by other researchs.The role of airborne sediments provides an illustration in soil genesis of the Mediterranean region.
