Abstract (in english)
   Miocene clays overlying the coal seams and transformed by earth fires into porcellanites represent a characteristic lithological member of the Most Basin. Due to their extremely fine grain size, their detailed mineral composition has been determined insufficiently yet. Among countless North Bohemian porcellanite localities, the abandoned quarry near the village of Dobrčice has been chosen and subjected to field as well as to laboratory study (chemical analyses, optical microscopy, X-ray diffraction and electron microprobe analyses). The following mineral phases werefound: mullite, tridymite,+-quartz, Fe, Mg cordierite, K-feldspar, calcic plagioclase, pyroxene, ilmenite, anatase or rutile, hematite, goethite, ulvöspinel, corundum, apatite and scarce monazite
