Abstract
the present contribution, the results of Mossbauer analyses of three t ypes of Slovak brown coal are presented. Electron microscopy and X-ray photoelectron spectroscopy were used as supplementary techniques. The dominant Fe bearing mineral was pyrite which contains from 78% up to 95% of the total amount of iron. The rest of iron is present in ferrou s carbonate (siderite) and silicate (illite) phases. In one of the thr ee samples a magnetically ordered component was identified.
