Constraining clastic input controls on magnetic susceptibility and trace element anomalies during the Late Devonian punctata Event in the Western Canada Sedimentary Basin

Terra Nova, 24, 301–309, 2012 Abstract Factor analyses were applied to trace element and magnetic susceptibility (MS) records of the Late Devonian palaeoceanographic ‘ punctata Event’ perturbation in the Western Canada Sedimentary Basin to constrain the extent to which geochemical anomalies were driven by 1) changes in clastic input (Factor 1; 55.1% of total variance) vs. 2) anoxia in the depositional environment (Factor 2; 35.2% of total...
