Sažetak
The paper deals with the relative sea level change along the Istrian coast. Sediments from two cores located in the bay of St. Marina and Soline Bay have been analysed for microfaunal and sedimentological investigations. Chronostratigraphical evidence was obtained from C14 dating of lagoonal shells (gastropods). From the sedimentological and paleo-environmental analysis, 4300 years of a continuous deposition in shallow marine environment was determined. At around 550 cal yr BP marine sedimentation passed to continental. Those continental deposits are today partly submerged. The obtained data were further compared with the local predicted sea level curve. As the results from the cores are largely below the predicted curve, the tectonic subsidence of the area was confirmed. If we adopt the assumption that the sedimentation rates are equal to subsidence rates we obtain a rates of 0.7 mm/yr, before 550 cal yr BP and 2.36 mm/yr after 550 cal yr BP. The obtained results were also related to the tidal notch development and to the GPS measurements.
