Sažetak
The Old City of Dubrovnik is on the UNESCO World Heritage list and is recognized as the “Pearl of the Adriatic” that adorns the southern coastal part of the Dinaric Karst. Both the southern and northern elevated parts of the Old Town are built on Mesozoic carbonate rocks deposited on the Adriatic Carbonate Platform (AdCP). The carbonate bedrock is strongly deformed since major compressional deformations of the AdCP succession began in the Eocene during the early orogenic thrusting and formation of the External Dinarides fold and thrust belt. The late orogenic complex tectonic deformations are still ongoing, and the area is characterized by occasional strong seismicity. The deformed packages of stratified limestones and dolomites of the Old Town bedrock show sedimentological features typical of peritidal subtropical sedimentation on the AdCP, while rare key microfossils allow age determination. The northern part of the Old City is situated on the Lower Cretaceous limestones while the southern part is built on the Upper Cretaceous dolomites. The central low-lying part of the town is built on anthropogenic infill of a narrow late Holocene embayment characterized by superficial Quaternary sediments overlying the heavily fractured carbonate bedrock. The exposed karst cavities are mostly filled with speleothems, indicating long-term karstification and denudation. The southern rocky shore is in patches covered by thin recent supratidal aragonitic encrustations known as pelagosite. Since geodetic data and coastal geomorphological features indicate recent surface deformations, the newly discovered geological structure of the Old Town of Dubrovnik should be taken into consideration during regional seismo-tectonic investigations.
