OverviewExcerpt from L'Algerie Les craies, les argiles, les calcaires et les marnes domi nent dans la composition du sol; les marnes argileuses surtout sont remarquables, elles contiennent en abondance des debris vegetaux et organiques; sur certains points elles presentent des epaisseurs de 100 metres. La plus grande partie des terrains se classent dans les series secondaires et tertiaires; en general, les grandes monta gnes, les hautes terres, toute la solide charpente du pays, ont ete construites pendant la periode secondaire; les formations tertiaires sont ensuite ve'nues rejoindre les parties separees, combler les intervalles en maconnant les petites montagnes et les plaines. Quelques fragments paleozoiques parsement encore la region septentrionale. Les atterrissements et les galets des plages, les alluvions dans les vallees du Tell et des hauts plateaux, les sables du Sahara ont ete fournis pendant la periode quaternaire.
