Detecting upland glaciation in Earth’s pre-Pleistocene record
(2022-08-08)Earth has sustained continental glaciation several times in its past. Because continental glaciers ground to low elevations, sedimentary records of ice contact can be preserved from regions that were below base level, or ... -
Loess in eastern equatorial Pangea archives a dusty atmosphere and possible upland glaciation
(2021-01)Carboniferous–Permian strata in basins within the Central Pangean Mountains in France archive regional paleoequatorial climate during a unique interval in geological history (Pangea assembly, ice-age collapse, megamonsoon ... -
Rock Magnetic Cyclostratigraphy of Permian Loess in Eastern Equatorial Pangea (Salagou Formation, South-Central France)
(2020-06-26)We present the findings from analysis and modeling of a stratigraphic series of magnetic susceptibility (MS) data measured with a portable MS meter from the Permian Salagou Formation loessite (south-central France). The ... -
A test of the efficacy of sand saltation for silt production: Implications for the interpretation of loess
(2020-07-21)Production of the silt that forms loess is attributed to processes operating in both glacial systems (glacial grinding) and sandy deserts (saltation-induced fracturing). However, the efficacy of saltation for significant ...
