Chemical weathering in glacial environments |

Potassium and calcium concentrations are high relative to other cations in glacial water, probably due to dissolution of soluble trace phases, such as carbonates, exposed by comminution, and cation leaching from biotite. Preferential weathering of biotite may result in higher 87 Sr/ 86 Sr in glacial runoff than expected from whole-rock compositions. Thus, although glaciers do not influence total chemical
