Abstract

New « puits naturels » (sinkholes) formed at Gaurain-Ramecroix in the Tournai area in 1988. They are related to a series of similar pits already formed in 1984. They are examined in relation with karstic phenomena observed in the quarry « Carrière du Milieu ». The sinkholes develop above horizontal caves, situated at 10 to 20 m below the land surface. These sinkholes are the consequence of a reactivation of a buried paleokarst. The reactivation is due to excessive pumping causing phreatic decline. - (L W)
