Abstract

Pri diplomski nalogi smo določili mineralne in geokemične značilnosti lončenine iz dveh spodmolov na območju Divaškega Krasa z arheoloških najdišč Mala Triglavca in Trhlovca. Raziskali smo 8 vzorcev neolitskih posod, ki so kulturno opredeljene v skupino Vlaška. Fragmente keramike smo najprej pregledali in opisali na makroskopski ravni, kjer smo ugotovili, da so nekateri barvni pasovi posledica sekundarnih sprememb, predvsem preperevanja (vzorca Vz4 in Vz7). Z uporabo optične mikroskopije in rentgenske praškovne difrakcije smo določili mineraloško sestavo. Kemično sestavo smo določili z rentgensko flourescenčno spektroskopijo, pridobljene podatke pa statistično obdelali. Vzorce lončenine smo na podlagi kombinacije rezultatov vseh metod razdelili v dve skupini. V prvo skupino sodita dva vzorca, kjer prevladuje kremen. V manjši meri so prisotna zrna muskovita, kalcita, plagioklaza ter hematitni agregati in glinena jedra. V drugi skupini pa so vzorci, kjer so glineni masi dodana zrna debelozrnatega kalcita. Keramiko te skupine sestavljajo v manjši meri kremen, muskovit, plagioklazov ter hematitni agregati in glinena jedra. Kemična sestava vzorcev je dokaj enotna in kaže na podoben izvorni material, razlike v vzorcih lončenine so predvsem v tehniki priprave gline. Glina, ki so jo uporabljali za izdelavo, je bila illitne sestave. Temperatura, pri kateri so bili vzorci keramike žgani,je določena od 600 oC in 700 oC.

Secondary title: mineralogical, petrological and geochemical analysis of Neolithic pottery from Mala Triglavca and Trhlovca
Secondary abstract: In diploma we determined mineral and geochemical characteristics of pottery from two rock-shelters in the area of Divaški Kras from archaeological sites of Mala Triglavca and Trhlovca. We were investigating 8 samples of Neolithic pottery which is culturally defined as Vlaška group. Firstly, we examined fragments of the pottery and described them on macroscopic level where we discovered that some colored bands were created by secondary changes, mostly because of weathering (samples Vz4 and Vz7). We determined mineralogical composition with the use of optical microscopy and X-ray powder diffraction. Chemical composition was detected with X-ray fluorescence spectrometry and the obtained data was statistically analysed. Pottery samples were divided into two main group. Two samples with predominant quartz belong to the first group. Muscovite, calcite, plagioclase, hematite aggregates, and clay cores are present as well. Samples with coarse-grained calcite added to the clay represent the second group. The pottery of this group is also composed of quartz, muscovite, plagioclase, and hematite aggregates, as well as clay cores. Chemical composition of the samples is quite unified and shows similar source material. Most differences between pottery samples origin from the preparation technique. Clay used for production was of illite composition. The temperature at which ceramics samples were fired is between 600-700oC
