N2 - The Middle to Late Anisian sedimentary succession preserved in theKlisura quarry in Sirogojno (Zlatibor Mt., SW Serbia) preserves the mostcomplete deepening depositional history in the Inner Dinarides in Serbia. Inthis section, extensional tectonic movements that took place in connectionwith the Neo-Tethys break-up are reflected in the exceptional well-preservedrecord of the depositional history. The Pelsonian Ravni Formation at the baseof the section is dissected by two generations of neptunian dikes formed in A)the late Pelsonian, and B) the late Illyrian. Above the late Pelsonian drowningunconformity a deepening trend of the depositional environment is mirroredby the litho- and microfacies characteristics of the more than 21 meter thickred nodular limestones of the Bulog Formation. Periods of starvation withdeposition of Fossillagerstätten beds and hardgrounds mark characteristicchanges in deposition. Two phases of distinct tectonic motions result inunconformities and a stepwise deepening of the depositional realm. The firstand major unconformity is the drowning surface on the top of the RavniCarbonate Ramp which led to the nearly total demise of shallow-watercarbonate production, i.e. the change in deposition from shallow- to deepwaterlimestones. The second phase of tectonic motions is expressed by theformation of an angular unconformity after a phase of starvation in the basin.No Bulog Limestone section in the Dinarides, even not in the type region nearSarajevo, preserves all these characteristic sedimentological features aspreserved in the Klisura quarry section in Sirogojno. Therefore this section isproposed to be the reference section for the sedimentological evolution anddepositional environment reconstruction of the Bulog Formation in the InnerDinarides, located in SW Serbia.
