Abstract

Poznavanje karakteristika sedimenta mora važno je radi općeg razumijevanja taložnog prostora, ali i radi poznavanja i predviđanja bioloških karakteristika morskog dna, te raspoređivanja zagađivala. Uz hrvatsku obalu odabrane su četiri lokacije s kojih je grabilom prikupljen morski sediment. Njemu su određivanjem veličine zrna, udjela karbonata te mikroskopskim pregledom definirane osnovne sedimentološke karakteristike. Svi uzorci sedimenta klasificirani su kao muljevi, s različitim udjelima pijeska i šljunka. Ove dvije frakcije čine uglavnom biogeni ostaci. Udio karbonata kreće se oko 30-60%, što ukazuje na prisustvo siliciklastične komponente u muljevitoj frakciji, a u njoj se vjerojatno nalazi i dio usitnjenih karbonatnih čestica. Svi analizirani uzorci su u skladu s taložnim okolišima uzimajući u obzir dubinu mora, zaštićenost od valova i donos terigenog materijala.

Abstract (english)

Knowledge of the characteristics of sea sediment is important for the general understanding of the depositional space, but also for the knowledge and prediction of the biological characteristics of the seabed, as well as the distribution of pollutants. Along the Croatian coast, four locations were selected from which marine sediment was collected with a grab. The basic sedimentological characteristics were defined by determining grain size, carbonate content and microscopic examination. All sediment samples were classified as silts, with varying proportions of sand and gravel. These two fractions consist mainly of biogenic remains. The proportion of carbonate ranges around 30-60%, which indicates the presence of siliciclastic components in the muddy fraction, and it probably also contains a part of crushed carbonate particles. All analyzed samples are consistent with depositional environments, taking into account the depth of the sea, protection from waves and the delivery of terrigenous material.
