A Revised Provenance Model for the Elk Mound Group in South-Central Wisconsin Based on Detrital Zircon Analysis
Get PDFThe Late Cambrian Elk Mound Group consists of three supermature sandstone formations deposited in and on the shores of a shallow, tropical sea: the Mount Simon, Eau Claire, and Wonewoc formations, in ascending order. Workers have used detrital zircon (DZ) U-Pb analysis to constrain the sources of the sand grains and build a regional provenance model. This study considers new samples from the Mount Simon Sandstone in the context of previous DZ studies in Wisconsin and Illinois. The samples reveal a transition from Mesoproterozoic source provinces towards Late Archean source provinces over time, which is understood to represent a shift from sediments derived from the more local Wolf River Batholith and Penokean orogenies to sediments derived from the more distal Superior Province. Such a shift likely reflects rising sea levels, which drowned local provinces and prevented their erosion while leaving more distal provinces high and dry. Along with the DZ data, paleocurrent indicators derived from optical borehole image logs from wells across central Wisconsin add to the regional provenance picture with evidence of currents predominantly flowing toward the west and southwest, giving some indication of the more immediate source and final transport of these sediments
The Role of Attention Control in a Mindfulness-Induced Reduction in Rumination: A Randomized Controlled Trial
No full textRumination is a transdiagnostic risk factor for various forms of psychopathology. Mindfulness, which focuses on the regulation of one’s attention, has shown to be effective at reducing rumination. Reductions in rumination also appear to mediate the effect of mindfulness interventions on improvements in psychological symptoms. However, the exact mechanism through which mindfulness reduces rumination is not well understood. Attention control, which has been previously implicated as the mechanism through which rumination increases symptoms and forms the basis of mindfulness, is of particular interest. In this study we recruited 48 high ruminating college students and randomly assigned them to a brief two-week mindfulness or active control intervention. Trait mindfulness, rumination, and attention control (measured through the antisaccade task and Emotional Go/No-Go task) were measured pre and post intervention. Our results showed a significant reduction in rumination following the intervention and suggest that this reduction was greater for the mindfulness group than for the control group. In addition, results of our mediation model suggested that rumination scores following the intervention were predicted by attention control prior to the intervention (measured by the antisaccade task). These results add to the growing body of research supporting the efficacy of brief mindfulness interventions in reducing rumination. Such treatments, which are lower in cost and time commitment, are important for reaching wider communities. In addition, the use of two tasks to measure attention control improved reliability and validity of this study while highlighting the critical need for emotional attention control measures
