Mineralogical and sedimentological characteristics of the sand of the Sava river from the wider surroundings of Zagreb : master's thesis

Cilj ovog diplomskog rada je granulometrijska i mineraloško-petrografska analiza, te morfometrijski opis uzoraka pijesaka rijeke Save. Ukupno je uzorkovano i analizirano šest uzoraka sa sljedećih lokacija idući od zapada prema istoku: Zaprešićki most, Podsusedski most, Jankomirski most, Domovinski most, Ikea (Drenje Ščitarjevsko) i Sisak. U Laboratoriju za analizu geoloških materijala na Rudarsko-geološko-naftnome fakultetu su rađene sljedeće analize: granulometrijska analiza suhim sijanjem laboratorijskim sitima, granulometrijska analiza laserskim granulometrom, separacija magnetske i nemagnetske mineralne frakcije Frantzovim izodinamskim magnetskim separatorom i separacija lake i teške mineralne frakcije tekućinama velike gustoće. Frakcije izdvojene separacijama su promatrane binokularnom stereoskopskom lupom kako bi se odredio mineraloško-petrografski sastav uzoraka i morfometrijske značajke zrna. Četiri uzorka su dominanto karbonatni pijesci, jedan uzorak je karbonatno-silikatni pijesak i posljednji uzorak je silikatnog sastava. Na temelju morfometrijskih karakteristika vidljivo je da su čestice dospjele iz različitih izvorišnih područja i da je vrijeme transporta bilo različito.The aim of this master’s thesis is the granulometric and mineralogical-petrographic analysis, and morphometric description of Sava River sediment samples. Six samples were collected and analyzed from the following locations, going from west to east: Zaprešićki bridge, Podsusedski bridge, Jankomirski bridge, Domovinski bridge, Ikea (Drenje Ščitarjevsko) and Sisak. In the Laboratory for the Analysis of Geological Materials at the Faculty of Mining, Geology and Petroleum Engineering were performed following analyzes: granulometric analysis by dry sieving with laboratory sieves, granulometric analysis by a laser granulometer, separation of magnetic and non-magnetic mineral fractions by Frantz's isodynamic magnetic separator and separation of light and heavy mineral fractions by high-density liquids. Fractions separated by separation were observed with a binocular stereoscopic magnifying glass to determine the basic mineralogical and petrographic composition of the samples and morphometric features of grains. Four samples are dominantly carbonate sands, one sample is carbonate-silicate sand, and the last sample is of silicate composition. Based on the morphometric features, it is evident that the particles arrived from different source areas and that time of deposition was different
