11 Weathering and chemical processes as keys to ecosystem functioning


Mark Smits (BE),
Heather Buss (UK)

Dienstag, 10:00-12:00, H20

Mineral weathering is the primary source of most elements essential to life and weathering processes play key roles in the dynamics of nutrient elements. The focus of this session is on the interactions between the living and the mineral world in soils and aquifers. Topics of interest include dissolution/precipitation, ion exchange, sorption and complexation processes. We especially encourage novel contributions that could bridge the fundamentals of geochemistry and ecosystem functioning.
