The glauconitic green shale at the basal part of the section is up to 1.5 m thick (Fig. 3 B). The lack of wave-originated structures and the fossil assemblage of the green shale suggest deposition under a quiet environment below the wave base. 3.3.2. Biostratigraphy and thermal eventsThe limestone–green shale alternation in the Valia mine is overlain by a ~4 m-thick spherulitic mudstone facies comprising monomineralic sideritic spherulites, reflecting a pure FeCO3 composition.
