| Further up the core into the Waulsortian sequence, the limestones are cleaner and the breccia clasts are cemented by calcite. |
| The ironstone is locally represented by hematite matrix-supported vein quartz breccia. |
| Eventually only a hollow lined by residual soils above a breccia chimney marks the site of a former salt extrusion. |
| Some 600 m below this breccia the pluton is pervaded by a fine-grained granophyre, apparently the product of a sudden and final crystallization. |
| The lower series consists of alternating basalt lava, tuff breccia, tufite, and siliceous rock, whereas the upper one is dominated by diabase. |
| The limestone-dolomite breccia is characterized by abundant palygorskite, minor sepiolite, rare kaolinite and near absence of smectite. |
