Early phases of mountain building are usually poorly constrained although they may provide insights into both the wedge rheology and role inheritance. In central Pyrenean Axial Zone, a main exhumation peak at 35–30 Ma is particularly well but previous stages much less constrained. this study, we present new low-temperature thermochronological zircon fission-track (U-Th)/He data structural obser...

Enzymatic activity during decomposition is extremely important to hydrolyze molecules that are assimilated by microorganisms. During aquatic macrophytes decomposition, enzymes act mainly in the breakdown of lignocellulolytic matrix fibers (i.e. cellulose, hemicellulose and lignin) that encompass the refractory fraction from organic matter. Considering the importance of enzymatic activities role...

In semiarid climates, a significant component of recharge to basin aquifers occurs along the mountain front. Traditionally called “mountain-front recharge” (MFR), this process has been treated by modelers of basins as a boundary condition. In general, mountain-front recharge estimates are based on the general precipitation characteristics of the mountain (as estimated, e.g., by the chloride mas...
