Environment/lithology: marine; shelly/skeletal limestone

• From Ref. 7488: "The Rabat-Tiflet area is a complex "anticlinal resp. anticlinorial" structure (W-E). The beds are folded in a mediotype style and disturbed by normal faults and several overthrusts of limited extent. Traces of isoclinal folding are rare. The folding is the result of the Hercynian (Variscan) orogeny. The R-T area is a typical region of the so-called Hercynian-Bohemian facies development of the Silurian and Devonian, moreover in facies and faunal development very reminiscent of the barrandian area...It is characterized by a complete marine succession, a conformable gradual transition from the Upper Silurian (Budnanian) into the early Lower Devonian (Lochkovian), without any effects of the Late Caledonian orogeny."
• Lithology based on stratigraphic column (see collection 27050, ref. 7484).
