Abstract
Na jezgrama NER3 i NER4 te iz rezultata preuzetih iz disertacije Felja (2017) za jezgre NER5 i NER6 iz područja deltne ravnice rijeke Neretve provedena je foraminiferska analiza, s ciljem da se rekonstruiraju taložni okoliši koji su se izmjenjivali tijekom holocena. U jezgrama je određena apsolutna brojnost foraminifera, relativna brojnost foraminifera i indeksi bioraznolikosti (indeks dominacije, Berger-Parker-ov indeks, Simpson-ov indeks, Shannon-Wiener-ov indeks, Fisher-ov indeks). Najzastupljenije vrste foraminifera pripadale su rodovima Ammonia, Haynesina i Porosononion. Povećanjem dubine rasla je i raznolikost vrsti, pa su nađene miliolide i jedinke roda Elphidium. Taložni okoliši koji su prepoznati na temelju indeksa bioraznolikosti i zastupljenosti foraminiferskih rodova su: aluvijalni okoliš (deltna ravnica), brakični okoliš (močvare/lagune, unutrašnji estuarij), te središnji/vanjski estuarij. Na temelju rezultata utvrđena je progradacija delte unutar estuarija te zapunjavanje estuarija tijekom holocena.
Abstract (english)
On the cores NER3 and NER4, and from the results given in disertation Felja (2017) for cores NER5 and NER6 from the area of the Neretva river delta plain, a foraminiferal analysis was carried out to reconstruct the depositional environments that were changing during Holocene. In all drilled cores total number of foraminifera, relative percentage of foraminifera and biodiversity indices (Dominance, Berger-Parker index, Simpson index, Shannon-Wiener index, Fisher's index) were calculated. The most common types of foraminifera belonged to the genera Ammonia, Haynesina and Porosononion. The biodiversity increased with depth and various miliolids and Elphidium genus were present in the deeper layers. Depositional environments that were recognized based on biodiversity indices and the abundance of foraminiferal genera are: alluvial environments (deltaic plain), brackish environments (marhes/lagoons, inner estuaries), central/outer estuaries. Based on the results, progradation of intra-estuarine delta and the filling of the estuarine basin occurred during Holocene.
