(a) OSL age-depth compilation of substrate formation for WSE and savannas in Amazonia, dashed gray lines represent different accumulation rates of sandy substrates; (b) 14C age-depth compilation of substrate formation for WSE and savannas in Amazonia. For these graphs, only profiles with 3 or more samples dated were considered.
