Weathering of an Antarctic Argillite: Field, Geochemical And Mineralogical Observations: NOTES

Paul Tasch, E. L. Gafford

ABSTRACT

Color stratification in carbonaceous argillites was quantitatively studied to obtain data on weathering under cold desert conditions (Antarctica, Ohio Range). The weathered outer light zone had markedly less organic carbon due to oxidation than the unweathered darker, inner zone. Trace element content did not significantly differ between the two zones. Illite (stripped form) characterized the inner zone and mixed layer clay the outer zone.
