Description :
This investigation uses a multidisciplinary approach including geomorphic surface mapping, soil stratigraphic analysis, radiocarbon dating and optically stimulated luminescence (OSL) dating to investigate the chronology of soil formation and aeolian activation periods recorded in ridge dune deposist as well as the spatial variability of aeolian processes during active aeolian episodes. This study shows that aeolian landforms superimposed on fluvial terraces adjacent to the Cimarron River, in southeastern Major County and northwestern Kingfisher County, are the product of distinct late Holocene climatic conditions, in which periods of dune activity are episodic and accumulation of sediments is relatively rapid.
