A great unconformity separates the Table Mountain and Ecca series.
Its distribution is very different from that of the Upper Cretaceous, and there is a great and widespread unconformity between them.
This unconformity is generally found about the same horizon in the continental Culm areas, and it occurs again in the western part of the English Culm.
From the Permian to the Lias the sequence in the central Himalaya shows no sign of a break, nor has any unconformity been proved between the Liassic beds and the overlying Spiti shales, which contain fossils of Middle and Upper Jurassic age.
Upon the folded slates and schists which constitute these inliers the Devonian rests with marked unconformity; but north of the ridge of Condroz Ordovician and Silurian beds make their appearance.
