ةpisodes majeurs de la podzolisation en forêt de Fontainebleau (France). Essai de synthèse à lʹaide du radiocarbone naturel

The sandy materials underlying the Fontainebleau Forest (Paris Basin) are often podzolised. Several radiocarbon datings reveal different periods of podzolisation: – the first millenary before Christ (aliotic podzols, often humic, over Stampian sands, very quartzic and acid – certainly under heather and pines); 0th to 12th centuries AD (humoferruginous podzols with Bh and Bs partially indurated, over blown sands, poor in fine particles – probably under heather); 6th to 17th centuries AD (ochrepodzolic soils on blown sands, richer in fine particles than precedent, and humic podzols upon eroded Stampian sands); ecently, not precisely dated (ochrepodzolic soils or podzols with loose Bh over blown sands, relatively rich in fine particles, sometimes under leafed trees). te this article: A.-M.
