Abstract:Raziskali smo kristale kalcita iz kamnoloma Liboje in jih primerjali s kristali kalcita iz drugih kamnolomov v širši okolici Celja. Pri kristalih kalcita iz kamnoloma Liboje prevladujejo kristalne forme položnega romboedra (012), ki se jim v kasnejši fazi kristalizacije pridružijo kristalne forme strmih romboedrov. Kristalizacija je potekala iz segretih vodnih raztopin znotraj razpok v karbonatnih kamninah. Ugotovili smo, da je rast kristalov kalcita iz Liboj povezana z vsaj dvema dogodkoma v geološki zgodovini, ko so se segrele vodne raztopine in posredno povzročile kristalizacijo mineralov v razpokah znotraj karbonatnih kamnin. Barva kristalov kalcita pa je povezana tako z vključki trde faze, kot so manganovi oksidi in goethit, kot s tekočinskimi vključki - vodo. Mineralno sestavo vključkov smo določili z ramansko mikrospektroskopijo.

Title:Morphological characteristic and causes of color for the crystals of calcite from Liboje
Abstract: The crystals of calcite from the quarry Liboje were investigated and compared with calcite crystals from other quarries in the surrounding area of Celje. In calcite crystals from the Liboje quarry, the crystal form of flat rhombohedron faces were predominant (012). At a later stage of crystallization, the crystal form of steep rhombohedrons prevailed. They crystallised from hot aqueous Solution in the fissures within carbonate rocks. It was ascertained that the crystal growth of calcite from Liboje was related to at least two events in geological history. The colour of calcite crystals is associated with both the solid phase inclusions, such as manganese oxide and goethite, and by liquid inclusions - water. Mineral composition of inclusions was determined by Raman microspectroscopy.
