Abstract
U svrhu određivanja koncentracije zlata u potoku Ludvić Samoborskog gorja uzorkovano je 13 uzoraka vodotočnog sedimenta koji su se ispitivanjem pomoću Goldspear uređaja na terenu pokazali perspektivnim. Drenažni teren sastoji se od raznih litostratigrafskih jedinica od kojih su najvažnije: P2,3, T1, T3, K2. Sijanjem je određen njihov granulometrijski sastav te parametri poput koeficijenta sortiranosti i koeficijenta asimetrije. Najperspektivniji uzorci su detaljnije obrađivani. Separacija mineralnih frakcija obavljena je pomoću Frantzovog izodinamskog separatora i bromoforma. Dobivene frakcije promatrane su kasnije binokularom radi utvrđivanja prisustva zlata i pratećih minerala. Uzorci su zatim otapani u zlatotopci te snimani pomoću atomske apsorpcijske spektrometrije (AAS).Koncentracija zlata je ispod granice detekcije (< 20 ppb). Uzorci su mljeveni u čeličnom mlinu i snimani metodom difrakcije na prahu (XRD).Iz difrakcijskih slika uzoraka određen je petrografski sastav. Detaljna determinacija petrografskog sastava obavljena je promatranjem uzoraka pod binokularom. Vidljivo zlato nije pronađeno. Određene su i matične stijene koje odgovaraju lokalnoj geologiji.

Abstract: In order to determine the concentration of gold in the stream Ludvić of Samobor hills, 13 samples of aquiferous sediment that have been analysed by Goldspear device, proved to be prospective. The drainage terrain consists of different lithostratographic units out of which P23, T1, T3 and K2 were the most dominant. Their granulometric composition was determined by sifting as well as respective parameters such as a coefficient of sorting and assymetry coefficient.Further analysis of the most prospective samples was conducted.The separation of mineral fractions was achieved by means of Frantz isodynamic separator and use of bromoform.The fractions obtained were closely examined by binocular in order to find the presence of gold and accompanying minerals. The samples were then dissolved in aqua reqia and photografed by means of atomic absorbtion spectometry (AAS).According to the results, the concentration of gold is below the boundary line of detection (<20ppb>).The samples were also grinded in a steel mill and recorded by XRD method. The diffraction photos of the samples helped to determine petrographic composition .Further determination of the petrographic composition was carried out by thorough observation under the binocular. As a result, visible gold was not found.Primary rocks that correspond to local geology were also determined.
