TL;DR: In this article, a comparative hydrogeochemical study of carbonate mineral equilibria and weathering fluxes in two NH carbonate-rich river basins is presented, showing that the ability of calcite and dolomite dissolution to keep pace with increased discharge indicates carbonate weathering is limited only by water flux and temperature dependent solubility in these watersheds.

TL;DR: In this article, the effect of elevated atmospheric CO2 on mineral weathering reactions in midlatitude carbonate-bearing forest soils of differing nutrient availability was investigated, where aspen and maple saplings were grown in open top chambers under two levels of atmospheric CO 2 and soil N.

TL;DR: In this paper, a field geochemical study of controls on carbonate weathering within rapidly circulating, shallow groundwater-surface water systems in the glaciated mid-continent region is presented.

TL;DR: In this article, geochemistry of soil, soil water, and soil gas was characterized in representative soil profiles of three Michigan watersheds, and the importance of silicate versus carbonate dissolution in the early stage of soil-water cation acquisition was defined.

TL;DR: In this article, the authors compared soil mineralogy and major element chemistry of soil waters from a carbonate free temperate aspen forest site in the Cheboygan watershed, northern Michigan, with that from carbonate-containing soils from experimental tree growth chambers (low- vs. high- fertility).
