AB  - In northern France and Belgium, a dark horizon enriched in organic matter is occasionally found within already well-known horizons developed on loess already attested, straddling the depleted and clay-enriched horizons. Discontinuous, preserved mainly at the lower points of the landscape, but in more or less well-drained conditions, it is interpreted as the local, basal, relic of a thicker humus horizon developed on calcareous loess at the beginning of the Tardiglacial period, forming a chernozem-type soil or similar, before decarbonation and clay migration. As it is always dissociated from the first valley-bottom deposits of the early Bølling period, we propose the hypothesis of a soil formed at the same time as these deposits, or even as early as the Oldest Dryas, before and/or during of the first decarbonation of the last loess deposits under a steppic vegetation cover.
