Experimentally determined solute release rates from variably metamorphosed shale : implications for weathering in the East River watershed, CO.
This study investigates the variability in solute release rates from samples of shale and slate with variable lithology resulting from contact metamorphism. Mineral dissolution column experiments are used to test the hypothesis that solute release rates will vary with metamorphic grade of Mancos Shale samples collected from the East River watershed in southcentral Colorado. To test if there is variation in solute release rates correlating to metamorphic grade in the East River watershed; flow through column experiments were performed at ambient temperatures ( 25C) in clear, acrylic columns ...
