Abstract

Interpretation of results obtained by this research describes and explains changes of depositional environments in the area of the Neretva River delta during Younger Pleistocene and Holocene, as well as influence of the sea-level changes on sedimentation and development of delta. Granulometric analyses were done on 38 samples from the core DP (119 m depth) extracted from the deltaic plain of the Neretva River. Results showed that the core could be divided in two parts: upper (0 - 30 m) and lower (30 - 119 m) part. The lower part of the core contains dominantly gravely and sandy sediments, which were probably deposited in the alluvial environments in the Younger Pleistocene, when the sealevel was much lower than today. In the upper part of the core, muddy sediment is prevailing, and this was interpreted as deposition after last glacial period, when sea flooded former Neretva River valley and created deep estuary. Results of calcimetry in the upper (muddy) part of the core showed values between 31% - 54% which reflects deposition in the conditions of carbonate-siliciclastic shelf, which are present today in the eastern part of the Adriatic Sea. Neretva River delta is the most significant delta in Croatian coast, with huge ecological and economic importance, and systematic researches of the evolution of the delta and processes in the delta could significantly contribute to its protection.
