متن کاملLithological Influences on Contemporary and Long-Term Regolith Weathering at the Luquillo Critical Zone Observatory
1 Lithologic differences 2 variable silicate weathering fluxes, which provide an important negative feedback on climate over 3 geologic timescales. To isolate the influence of lithology on weathering rates and mechanisms, we 4 compare two nearby catchments in the Luquillo Critical Zone Observatory in Puerto Rico, which 5 have similar climate history, relief and vegetation, but differ in bedrock...
متن کاملReassessing rainfall in the Luquillo Mountains, Puerto Rico: Local and global ecohydrological implications
Mountains receive a greater proportion of precipitation than other environments, and thus make a disproportionate contribution to the world's water supply. The Luquillo Mountains receive the highest rainfall on the island of Puerto Rico and serve as a critical source of water to surrounding communities. The area's role as a long-term research site has generated numerous hydrological, ecological...
متن کاملThe importance of non-carbonate mineral weathering as a soil formation mechanism within a karst weathering profile in the SPECTRA Critical Zone Observatory, Guizhou Province, China
Soil degradation, including rocky desertification, of the karst regions in China is severe. Karst landscapes are especially sensitive to soil degradation as carbonate rocks are nutrient-poor and easily eroded. Understanding the balance between soil formation and soil erosion is critical for long-term soil sustainability, yet little is known about the initial soil forming processes on karst terr...
متن کاملGeochemical behaviors of different element groups during shale weathering at the Susquehanna/Shale Hills Critical Zone Observatory
Major and trace element concentrations were measured in bedrock, regolith and stream sediments from a first-order catchment developed entirely on grey shale in central Pennsylvania, USA. These elements can be classified into five major groups based on statistical data analysis. The presence of different elemental groups is due to the mineralogical origin, cycling processes, and geochemical prop...
