Croatian Dinarides zone which consists of External Dinarides transition zone, (high karst zone) ,Central zone, Dinarides frontal thrust, SW marginal zone, slope zone of Dinarides Platform and Adriatic Basin is an extended zone of the Alps. Hydrocarbon shows were detected in some wells which were drilled in the Central zone (close to the town of Zadar). The area of interest in this study is Knin-Ravni Kotari and eastern part of the Adriatic Basin.Knin high karst zone and Ravni Kotari with weathering zone reproduce very low signal to noise ratio on seismic lines. Seismic image of these seismic lines is not suitable for reliable seismic, nether for geological-structural interpretation. Satisfactory seismic image was obtained by applying certain seismic algorithms in these seismic lines reprocessing. By applying these seismic lines and combining them with geological maps and wells data we have made geological-structural profile of External Dinarides transition zone to eastern part of the Adriatic Basin. On this profile we have reconstructed better geological-structural relation of this area and also zones for potential hydrocarbon traps.
