  • Abstract A substantial part of the mineralogical and chemical heterogeneity of clay-poor sands, at the bed scale, results from tractive redistribution of the grains in the bedload. Since coarse and light particles are more easily entrained than denser and smaller heavy minerals, the latter commonly concentrate in grain scale lags, that alternate with sand depleted in these minerals. When sampled and analysed at the centimetre scale, this primary heterogeneity translates into nice geochemical… CONTINUE READING
