X-ray diffraction analyses of samples from cave fills in Slovenia
Bosák, Pavel; Melka, Karel; Zupan Hajna, N.
2004 - English Totally 85 X-ray diffraction patterns were performed from 21 samples of cave sediments from various caves in Slovenia. The most interesting are samples Nos. 15 and 16 composed nearly completely by smectite. Randomly interestratified structure of chlorite (60 %) and smectite (40 %) was identified in samples Nos. 9 and 10. Admixtures of magnetite (No. 4), haematite (Nos. 4, 13), goethite, (No. 14) and boehmite (No 13) were recorded in some samples. Phyllosilicates are mostly represented by chlorite, mica, micaceous mineral (illite?), in lesser extent by kaolinite and in one sample probably by vermiculite (No. 11). Quartz and sometimes calcite represent prevailing minerals. Feldspar (mostly plagioclase) is common constituent, nevertheless in lesser amounts. One sample (No. 11) contained amphibole. Na 21 vzorcích jeskynních sedimentů z různých jeskyní na Slovensku bylo stanoveno celkem 85 rentgenově difrakčních schémat. Nejzajímavější byly vzorky 15 a 16, které obsahovaly téměř výhradně smektit. Nepravidelně rozvrstvené struktury chloritu a smektitu byly zjištěny ve vzorcích 9 a 10. V některých vzorcích byly nalezeny příměsi magnetitu, hematitu, goethitu a boehmitu. Fylosilikáty byly většinou zastoupeny cloritem, slídou a slídnatými minerály, v menším množství kaolinitem a v jednom vzorku pravděpodobně i vermikulitem. Křemen a kalcit představovaly převažující minerály. Živec (většinou plagioklas) byl běžně zastoupen, ale v menším množství. Jeden vzorek (11) obsahoval amfibolit.
