Sandstones and conglomerates Peruc Mbrs (lower Cenomanian , Upper Cretaceous ) of eastern Bohemia and coal mass in them
 Martinec, Petr ; Kubina, Lukáš ; Rojáková, T.
A reasonably complete knowledge of the development of East Bohemia’s Lower Cenomanian sediments (Peruc Mbr) is still lacking. The sediments originate from rivers flowing from the buried Hořice-Nové Město elevation to Moravia in the SE direction, via a flatland depression. The sandstone and conglomerate bodies within the Litice Chlum area under investigation are channel river sediments accompanied by sedimentation in river lakes or oxbow lakes. The landscape of the region showed the character of a low-relief peneplain. At Sopotnice site, the surface of Litice kaolinite massif of granodiorite with a weathered crust incorporates fine-grained conglomerates with white quartz and quartzite pebbles in a sandy matrix. They form wedge-shaped channel bodies of several dozens centimeters thickness. The textures are massive, with inconspicuous positive gradation bedding of medium to poor bed sorting. By their character they correspond to the fill of an instable riverbed that kept changing its position in the flatlands. In the matrix, kaolinite dominates over illite.

Czech and Polish Conference Geology of Coal Basins /9./
 Kožušníková, Alena ; Ruppenthalová, Lucie
Department of Laboratory Research on Geomaterials of the Institute of Geonics AS CR has organized the Czech - Polish conference about geology of coal basins since 1993. Traditionally, at the conference meet experts especially from the Czech Republic and Poland, dealing with the development and research of coal deposits, geology of the coal basins, tectonics and coal petrography. However, with new trends in the use of coal deposits, there are also presented the results of research in physical and chemical properties of coal and coal mass, pyrolysis and combustion processes or geosequestration of CO2 into coal seams.
