The "Oolite Ferrugineuse" (Thurmann 1832) (not shown in Fig. 4a) occurs locally
within the Grenchenberg Beds. These iron-oolites consist of sparry, bioclastic limestones containing coarse arenitic echinoderm fragments and iron-oolites. Typically, oblique stratifications alternate with centimeter-thick marl layers.
