The brochure titled “25 years of research in the Lesní potok model catchment” (in Czech)
The Academia Publishing House presents individual research programmes within the publication edition of “Strategie AV21”. One of the programmes is the “Life Diversity and Ecosystem Health” contributed by the Institute of Geology CAS. The activities of this programme are coordinated by the Biology Center of the Czech Academy of Sciences. One of the most recent outputs of this programme was the brochure titled “25 years of research in the Lesní potok model catchment” (in Czech). The brochure is authored by Tomáš Navrátil, Jan Rohovec and Petr Skřivan.
Workshop “Potential of lithium mining in the Czech Republic and its use in advanced technologies”
Workshop “Potential of lithium mining in the Czech Republic and its use in advanced technologies” was held on October 17, 2016, within the cooperation between the Czech Academy of Sciences and the Chamber of Deputies of the Parliament of the Czech Republic. The scientific programme of the workshop was organized by Karel Breiter of the Institute of Geology CAS. Five talks given by foremost specialist of the Academy of Sciences, universities, Czech Geological Survey and mining companies covered topics ranging from geological exploration, through mining and processing of lithium in the Czech Republic, to potential use of lithium in energy storage.
Research Reports 2015
Research Reports 2015 - the annual report on scientific activities of staff of the Institute of Geology – has been newly published.
Straddling the range from gold grains to Moon dust: automated scanning electron microscopy
Do you need to support mineral prospection by automated mineralogy and artificial intelligence? Do you need to build a platinum concentrator? Do you need to find a particular dust particle in a million? Do you need to assess the risk of environmental pollution? Or to mix up a bucket of Moon dust? In all these tasks, automated scanning electron microscopy proves useful by integrating millions of individual measurements.
Photogenic Science
Photographs taken by the staff of the Institute of Geology were successful again in the third run of the Photogenic Science contest. In the “Photogenic Science” category, the professional jury and the Academic Board awarded the 2nd, 3rd and 4th positions to photos “Dead mire” and “A world in a drop of water” by Jiří Sláma. In the “Scientists on photographs” category, the 2nd position was awarded by the professional jury to Michal Filippi for a photo named “On the bottom”. In addition, the following photos were selected for the semi-finals: “Dancers” and “Races in the rain” by Pavel Lisý, “Talking rocks” and “Burning fire” by Jiří Sláma and “Painting” by Michal Filippi. The honoured photographs will be included in the Calendar of the Academy of Sciences. Some other photos from the semi-final selection are being used in promotion materials of the Academy of Sciences.

A new popular-science book on the landscape evolution of the Křivoklátsko Protected Landscape Area
Two staff members of the Institute of Geology AS CR, Karel Žák and Václav Cílek, became authors of a new book on the landscape evolution of this nature-protected area. The book reviews landscape evolution since the oldest geological past until the present time (Křivoklátsko – The Story of the Royal Hunting Forest by K. Žák, M. Majer, P. Hůla, V. Cílek). The book was published with the financial support of the Central Bohemian Region in the Dokořán publishing house. The photos were taken during the launching ceremony of the book, which was held at the Křivoklát medieval castle on September 23, 2016.
Ladislav Slavík appointed secretary of the International Subcommission on Devonian Stratigraphy
RNDr. Ladislav Slavík, CSc. of the Institute of Geology CAS has been appointed a secretary of the International Subcommission on Devonian Stratigraphy ICS, IUGS. He has started his new term for the next four years (2016–2020) after the Meeeting of the International Commission on Stratigraphy that was held at the 35th International Geological Congress in Cape Town, South Africa in August 2016.
Toxic metals revealed to be absorbed by mycorrhizal fungi at plant roots
Jan Borovička and his co-workers have published a study on the accumulation of toxic metals and other elements in ectomycorrhizal roots of Norway spruce (Environmental Pollution, Impact Factor: 4.839). Their research was conducted in the Příbram area, subjected to long-lasting man-induced pollution from ore mining and processing. When compared to non-mycorrhizal tiny spruce roots and organic soils, concentrations of metals (cadmium and silver in particular) were significantly elevated in ectomycorrhizal roots. This phenomenon can be attributed to metal-binding capacity of fungal mycelia. These results support the hypothesis that mycorrhizal fungi may protect host plants against heavy metal toxicity in polluted environments.
Microbial precipitates in old iron ore mines (central Bohemia)
One of the preserved galleries in the former iron-ore mining district of Zdice (35 km SW of Prague) originated between 1950 and 1965. The iron-rich layer, Ordovician (460 million years) in age, was found to be of low thickness and low grade to be economic. The present study of the gallery is focused on presently forming secondary precipitates of iron and calcium compounds. It is likely that some of the precipitates are microbially induced, with a significant involvement of iron bacteria. Photo gallery.
