Geokemična in mineraloška karakterizacija vrtine iz visokega barja Šijec = geochemical and mineralogical characterization of borehole from bog Šijec : diplomsko deloHorvat, JurijZ analizo barjanskih sedimentnih vzorcev iz barja Šijec, ki so bili odvzeti iz 7 m globoke vrtine, smo poskušali ugotoviti mineralno sestavo anorganskega materiala, njegov izvor ter tip ... sedimentacije, ki je potekal za časa odlaganja analiziranega odseka. V ta namen sem pripravili 37 vzorcev. Analizirani vzorci izhajajo iz globine 588-711 cm in predstavljajo odsek, v katerem delež anorganskega materiala močno naraste. Zgornja polovica vzorcev je bila sežgana, na drugi polovici vzorcev pa smo skupaj s pepelom iz prve polovice opravili še rentgenske analize. Rezultati žganja kažejo, da po naglem začetnem povišanju organskega deleža, ta z globino vztrajno upada, in to vse do količinske prevlade anorganske komponente, ki se dovrši pri zadnjih dveh žganih vzorcih iz globine 648 in 652 cm. Iz rezultatov rentgenskih analiz je razvidno, da v vzorcih prevladuje kremen, vsebujejo pa še glinene minerale, sljude, plagioklaze in karbonatne minerale, ki se pojavijo v vzorcih iz globlje polovice analiziranega intervala. Na podlagi rezultatov žganja sklepam, da predstavlja analiziran odsek prehod iz pretežno minerogene (jezerske) sedimentacije v organsko sedimentacijo, značilno za barja. Pri primerjavi mineralne sestave vzorcev iz analiziranega segmenta vrtine s sestavo okolnih kamnin sem ugotovil, da se večina anorganskega materiala pojavi v neposredni okolici barja in tako vir za večino jezerskega materiala predstavljajo kamnine iz povodja barja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
