摘要

Parameters spatial distribution of the solution pipes in the chalk of the north western Paris Basin shore clif. - The north western extremity of the Paris Basin consists of chalk), shore cliffs. At the top of this cliff wall, we find solution pipes with variable morphometric characteristics. The alms of this work arc the study of the spatial distribution of solution pipes and the determination of parameters which explain this distribution (lithology and fracturation of chalk, base level, cover of Cenozoic superficial deposits).
