The Veterlin reef complex is formed by a 600–1200 m thick sequence of Upper Ladinian to Lower Carnian carbonates, which may be divided into slope megabreccia, calciturbidites and grain flow deposits, fore-reef detritic limestones, biogenic limestones of reef cores, and back-reef and organogenic cyclic, often dolomitized limestones. The article describes the microfacial, geochemical and biofacial features of individual zones, and the special features of the diagenetic development of the carbonate reef complex.
