The present state of knowledge regarding the Moravian Painted Ware culture fortified settlement at Hluboké Mašůvky (Znojmo district)
Čižmář, Z. ; Čižmář, M. ; Lisá, Lenka
Despite its special place in the awareness of the professional public and in the literature, the oft-investigated Neolitic site at Hluboké Mašůvky-"Nivky" has still not been processed as a whole. The information available come s from a range of finds reports, some published, studies bosth large and small and above all the major finds assemblage of the "Vildomec collection" and the National Museum in Prague. The field excavation methods of the pre-war period, with no detailed general plan of all the investigated features and areas, and a lack of systematic stripping within the fortified area, have resulted in imprecise information that must be reviewed. This paper takes on this challenge, employing the results of rescue excavations undertaken on the site in 2003 by the Institute for the Archaeological Heritage, Brno.

Bioeroze v geologickém záznamu České republiky. Exkurzní průvodce pro předkonferenční exkurzi 4. mzn. konference o bioerozi. 22.-28. srpna 2004, Česká republika
Mikuláš, Radek
Geological record of bioerosion of the Czech Republic represents a great stratigraphic range, variety of settings and diverse substrates. We have to mention microborings in the probable Late Proterozoic stromatolites, bored bioclasts of the Silurian and Devonian, Devonian and Carboniferous hardgrounds and rockgrounds, rare wood borings in the Permian deposits (Bohemian Massif), Jurassic transgressive and reef facies, Early Cretaceous rockgrounds (Carpathians), Upper Cretaceous bored rockgrounds, bioclasts and wood (Bohemian Massif), Cenozoic borings in wood, leaves, fruit stones and bones (Bohemian Massif), bioclasts and rockgrounds of the Miocene bottom and sedimentary fill of the Carpathian Foreland and the Vienna Basin. Several Pleistocene and Holocene archaeological sites contain the record of animal and plant bioerosion coupled with the human activity.

Sborník abstraktů ze 4. mezinárodní. konference o bioerozi
Forty-four international contributions on bioerosion from the fossil record and from modern settings show that the first intensively bioturbated substrates were carbonate hardgrounds, soon followed by carbonate bioclasts. By the end of Paleozoic, wood bioerosion starts to take place; marine bioerosion in lithic substrates have much diversified during the Cretaceous and Cenozoic. The set of extended abstracts also shows increasing interest on mammals as tracemakers, and on bioerosion on non-marine settings.

Cenozoické vulkanické série v západní části Českého masívu
Ulrych, Jaromír ; Novák, Jiří Karel ; Lloyd, F. E. ; Balogh, K. ; Hegner, E. ; Viereck-Götte, L. G.
The western part of the Ohře/Eger Rift is a geodynamically active area in the Alpine foreland. Associated Cenozoic alkaline volcanism, particularly that of Quaternary age, plays an important role in the seismic active region of the W Bohemia and Saxony and is accompanied by intensive manifestations of mantle degassing (CO2, He, N). Three Tertiary to Quaternary alkaline volcanic rock series were recognised there: 1. Early Oligocene to Early Miocene (31-20 Ma) in the Doupovské hory Mts. and western Ohře Riftu. 2. Middle to Late Miocene (16-8 Ma) associated with the Cheb-Domažlice Graben. 3. Pleistocene (0.43-0.26/0.11 Ma) associated with the Ohře Rift and Cheb-Domažlice Graben junction. On the basis of isotopic and geochemical data of the primitive mafic volcanics of all series the source of magmas is a sublithospheric HIMU mantle source.

Rentgenově difrakční analýzy vzorků z výplní jeskyní ve Slovinsku
Bosák, Pavel ; Melka, Karel ; Zupan Hajna, N.
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.
