It is shown by pollen analysis and radiocarbon datings of two bogs that an Ericaceae moor grows on the granitic heights of eastern Minho (Northern Portugal) from the end of the 1st millenary A.D. Unprotected by this moor, the granite is superficially weathered it explains the detrital feature of these organic deposits. Before, a forest would protect substratum and its quick destruction is of human cause.Les analyses polliniques et radiométriques de deux tourbières montrent qu'une lande à éricacées s'est développée des la fin du 1 er millénaire de notre ère sur les sommets granitiques de l'Est du Minho (Nord Portugal). Mal protégé par cette lande, le granite a depuis subi une désagrégation superficielle qui explique le caractère détritique d...
