Abstract

Ovaj rad se bavi analizom pleistocenskih glinovitih naslaga na području Grba u
okolici grada Nina. Uzorci su prikupljeni iz tri bušotine te su provedene mineraloške
analize sedimenta. Kvalitativnom rendgenskom analizom neorijentiranih preparata dobiven
je cjelokupni sastav uzoraka. Snimljeni rendgenogrami su prikazali prisutnost kvarca,
kalcita i minerala glina. Kalcimetrijom je određen udio karbonatne komponente svakog
uzorka. Za potrebe izrade orijentiranih preparata za kvalitativnu rendgensku difrakcijsku
analizu uklonjeni su karbonati i organska tvar. Snimanjem orijentiranih uzoraka
identificirani su minerali glina na temelju njihovih karakterističnih bazalnih maksimuma.
Minerali glina koji se pojavljuju su smektit/smektit-klorit, illit, kaolinit, te ponegdje
vermikulit i miješanoslojne gline. Dio uzoraka pročišćenih od karbonata i organske tvari je
korišten i za određivanje kapaciteta kationske izmjene (CEC). Ova metoda se provodila
upotrebom bakrovog etilendiaminskog kompleksa.

Abstract (english)

The aim of this Master’s thesis was to analyse Pleistocene clay sediments near
Grbe in the vicinity of Nin. Samples were collected from three drill holes and
mineralogical analysis was performed. By qualitative X-ray diffraction (XRD) analysis of
unoriented samples, overall composition of the samples was obtained. XRD analysis of the
unoriented samples showed the presence of quartz, calcite, and clay minerals. Calcimetry
determined the amount of carbonate component in each sample. For the purpose of making
oriented mounts for the qualitative XRD analysis of clay fraction, carbonates and organic
matter were removed. Clay minerals were identified based on their characteristic basal
reflections. The clay minerals occurring in the samples are smectite / smectite-chlorite,
illite, kaolinite, and in some cases vermiculite and mixed-layered clays. A portion of the
sample after removal of carbonates and organic matter was used to determine cation
exchange capacity (CEC). This method was performed using a copper ethylenediamine
complex.
