Résumé

The karstic network of the Lomme river – The most remarkable geositesThe cave of Pré-au-Tonneau illustrates the genesis and the complex evolution of a karstic network. Originating at first in depth, independently of the surface relief, voids get organized, along lines of deep water circulations and can generate by place pressure pipes. Brought out and laterally cut by the digging of the Lomme valley, voids connect to the river and drain a part of surface waters. Of a “simple” underground network, isolated of the surface, the cavity is sometimes transformed into swallow hole. At the same time, the various fissures (joints, stratification plans), widened by the vadose seepage, cut and gradually disrupt the morphologies inherited from the phreatic environment.
