Summary

Comprehensive sampling of peat, underlying lakebed sediments, and coexisting waters of a naturally uraniferous montane wetland are combined with hydrologic measurements to define the important controls on uranium (U) supply and uptake. The major source of U to the wetland is groundwater flowing through locally fractured and faulted granite gneiss of Proterozoic age. Dissolved U concentrations in four springs and one seep ranged from 20 to 83 ppb (µg/l). Maximum U concentrations are ~300 ppm (mg/kg) in lakebed sediments and >3000 ppm in peat. This study documents the conditions and processes controlling the efficient uptake of U in a relatively remote, natural wetland that is absent of reported U occurrences, mining impacts, or other [...]

Purpose

The purpose of this data release is to provide machine-readable tables of data used to create maps, figures, statistical and geochemical analyses, and the 3-dimensional subsurface stratigraphic model presented in the Applied Geochemistry article (https://doi.org/10.1016/j.apgeochem.2017.01.001), as well as additional data that were collected in the Boston Peak wetland as part of the study, but were not included in the journal article, which may be of interest or use to wetland researchers.
