Stratigraphy
| Formation: | Gabian | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: The fossil content of this formation, mainly consisting of characteristic elements of the brachiopod Nicolella Community, allows for correlation with other Upper Ordovician Mediterranean bioclastic limestones and dolostones, such as the Uggwa Limestone and Wolayer formations from the Carnic Alps, Austria (Schönlaub 1998), the Estana Fm. from the Spanish Central Pyrenees (Gil-Peña et al. 2004), the Cystoid Limestone from the Iberian Chains (Villas 1985), the Portixeddu and Domusnovas formations from Sardinia (Leone et al. 1991), the Rosan Fm. from the Armorican Massif (Mélou 1987), and the Upper Djeffara Fm. from Libya (Buttler & Massa 1996). | |||||

| Lithology description: At its type section the lower part of the formation is characterised by 4.5 m of alternating marlstones with isolated shelly fossils and bioclastic limestone beds up to 10 cm thick. The upper part is made up of laminated massive bioclastic marly limestones rich in bryozoans and cystoids, of which only 2 m crops out below Quaternary beds. The total thickness of the unit was estimated at 10 to 25 m by Dreyfuss (1948). | |
