Abstract

This work quantifies the erosive processes in the 2 main substrates (schists-phyllites and granites-gneisses) of the upper Maracujá Basin, a region of semi-humid tropical climate. Two measuring methods of concentration were used : in situ produced Be 10 in quartz veins (surface erosion rates) and Be 10 in fluvial sediments (basin erosion rates). The results confirm that erosion tends to be more aggressive close to the headwaters than in the lower parts of the basin, and the region is now affected by dissection
