The orientation of the scientific research activities

of the Department members has exhibited considerable shift towards practical tasks of environment protection and unfolding of the cooperation with industry (brickworks, incineration plants, pharmaceutical plants, construction and building enterprises). This shift has been enabled by substantial modernisation of the intrumentation located at the Department. Modern microanalytical equipment has established sound basis for novel cooperation with scientific institutions of the Czech / Slovak Academy of Sciences and many universities (Technical University Košice, Comenius University Bratislava, other faculties of the Masaryk University, Military High School in Vyškov, Faculty of Science of the Charles University in Prague).

Besides traditional petrological study of natural radioactivity of rocks from the Paleozoic of the Central Moravia (J. Stelcl in corroboration with Military High School in Vyskov and Administration of the Moravian Karst Preserve), collaboration in the field of archeological research (localities Znojmo, Břeclav and Brno - J. Stelcl, M. Gregerová), petrological evaluation of igneous rocks of the Brno Massif (M. Gregerová), works in new scientific objectives have been initiated.

M. Gregerová has continued the study of rock-forming minerals of the Brno Massif and the chemism of its rocks. She has also extended the study of weathering processes observed in building stones of the historical town centers and the deterioration of calcite/aragonite of the Zbrasov Cave. She has continued the study of graphite ceramics from the Moravian region.

Senior lecturer D. Nemec has studied the genesis of skarns of the Moldanubicum and their relationship to amphibolites.

Prof. M.Suk has brought his attention to the research of rocks of abyssal origin occurring in the Moravian crystalline complexes. He carried on with the genetic interpretation of granulite rocks, with study of the relationship between eclogites, peridotites and amphibolites of the Moldanubicum, and with synthetic work on the role of the Precambrian in the lithosphere of the Central Europe and the significance of the erosional cut for the interpretation of geological structure. In correspondence with the educational needs, he has also solved some regional geologic problems.

In geochemistry, oxidation-reduction potential in the natural environment has been studied by senior lecturer J. Zeman, as well as the interaction of water, sulfides and rock environment and the influence of bacteria on the oxydation of arsenopyrite. The problems of heavy metals release and acidification met at ore deposits and slurry settling ponds, and the possibilities of stabilization of acid mine waters have been studied by K. Martycak.

In the mineralogical field, Z. Losos has presented and successfully defended a PhD. Thesis concerning mineralogical, structural and geochemical research of graphites from North Moravian and Silesian deposits.

Prof. B. Fojt proceeded in genetic evaluation of iron ore occurrences and sulfide parageneses in the same area (published results from Maly ded and Hranicna localities). The simultaneously obtained data on sulfide mineralization of the Zulová (Friedberg) Massif were presented at the international conference held at Geyer, Germany (Z. Losos, B. Fojt). During all above studies, cooperation with the Isotopic Laboratory of the Czech Geological Institute in Prague (J. Hladíková) and the Brno branch of the same institute (J. Horák) has successfully been extended.

Prof. J. Stanek has studied in close corroboration with P. Cerný from the University of Manitoba in Winnipeg and M. Novák from the Moravian National Museum in Brno the mica minerals from pegmatite occurrences Rozna and Dobra Voda (presented for publication). Furthermore, he has studied the chemism of granitoid and pegmatoid rocks of the West Moravian part of Moldanubicum and minerals of the beryl-columbite type of pegmatite in Marsikov, North Moravia.
