From the micromorphology of paleoweathering fronts to paleoenvironmental analysis: A case study of the Cretaceous dune fields of Sanfranciscana Basin, Brazil
2022, CatenaCitation Excerpt :The preservation of inland aeolian systems without the influence of coastal lines, as observed in Sanfranciscana Basin, is a necessary three-stage process (i) construction of an eolian dune-fields; (iii) sediment accumulation to form a succession; and (iii) long-term burial and incorporation into the geological record (Kocurek, 1999). The paleogeography of the sedimentary basin inextricably links the development of this process, tectonic regime, and the atmospheric circulation that directly affects sediment supply (Kocurek and Lancaster, 1999; Mountney and Jagger, 2004; Rodríguez-López et al., 2014; Lancaster and Mountney, 2020). The sediment budget can be positive, neutral, or negative, generating different types of supersurfaces that define a sequence boundary (Kocurek and Havholm, 1993).
