glacial drifts of the late ice age into the ice-free forelands, as well as the annual clay-silt sediments in the floodplains of rivers (e.g. the Nile before the construction of the Aswan Dam) and the deposition of volcanic ashes. The latter were used in antiquity throughout the Mediterranean region to improve marginal soils. The rejuvenation of ageing soils or naturally acid sites through marling — that is, through the application of loose, easily weathered, lime-rich clay rock — has been widespread practice since at least the edict of Charles the Bald (823–877) from the year 864. The range over which such heavy masses could be transported was, of course, limited.
