Braided rivers have accumulated a dominant fraction of the terrestrial sedimentary record, and yet their morphodynamics in proximal intermountain reaches are still not fully documented—a shortcoming that hampers a full understanding of sediment flu

The Sudbury Basin is a unique, regional geologic and geomorphologic feature situated on the southern Canadian Shield at the nexus of three geological provinces and three physiographic zones. Its broad form is attributable to its meteorite impact orig

Previous evidence for fragments of a cosmic airburst in the Western Alps has been shown to reside in weathering rinds in surface clasts of Late Glacial (LG) (mid-LG-post Allerod) deposits and in Ah horizons of several associated paleosols. In contras

Understanding the mechanism associated with rates of weathering and evolution of rocks→sediment→soil→paleosol in alpine environments raises questions related to the impact of microbial mediation versus various diverse abiotic chemical/physical

Weathering rinds have been used for decades as relative age indicators to differentiate glacial deposits in long Quaternary sequences, but only recently has it been shown that rinds contain long and extensive palaeoenvironmental records that often ex

The sediments of Frame Lake, Yellowknife, NWT were examined to evaluate human impact due to urbanization and mining and provide background information for potential remediation efforts. Physical and geochemical analyses were carried out on cores from
