Evaluating control of slope-aspect on geochemical weathering within the Boulder Creek Critical Zone Observatory
MetadataShow full item record
Geochemical weathering in the Critical Zone is an important source of mobile regolith and solutes that drive landscape evolution and nutrient cycling. An in-depth understanding of geochemical processes is integral to prediction and evaluation of Earth surface response to natural and anthropogenic perturbations such as global climate change and land use. This study evaluates chemical and mineralogical changes from the surface to depths >15 m in the Gordon Gulch watershed of the Boulder Creek Critical Zone Observatory and investigates hillslope aspect control of weathering processes. These data ...
