Some aspects of mercury records in tree rings
Tree-rings as a geochemical archive were presented as a topic studied within the Department of Environmental Geology and Geochemistry of the Institute of Geology CAS. The article describes some aspects of mercury records that can be deciphered from Larch and Pine tree rings as well as some peculiarities of the associated fieldwork. In Czech only.
Molybdenum isotopic signal survives in ancient, strongly metamorphosed rocks, a new study revealed
Molybdenum isotopic composition (98Mo/95Mo) provides important clues to paleoenvironmental changes of the Earthʼs oceans and atmosphere throughout the geological history. Previous studies were predominantly focused on black shales which reflected the degree of atmosphere oxygenation. Nevertheless, the new study published in the Scientific Reports journal (link here), also contributed by the Institute of Geology CAS, revealed that even ancient rocks (~2.1 Ga Mn ores from Brazil), which underwent high degrees of metamorphism (> 600 °C) retain Mo isotopic signal. Thus, these data argue for the presence of oxic–anoxic-stratified Palaeoproterozoic oceans. This is the first contribution since the new Mo isotopic methodology has been established in the joint laboratory of the Institute of Geology of the Czech Academy of Sciences and Czech Geological Survey.
Article on dust particles published in the ABC journal
Images of dust particles from a number of case studies performed at the Institute of Geology CAS were published in the popular ABC magazine as a part of the science-promotion project Strategie AV21, Natural Hazards. The article "InVisible Army – Dust everywhere you look" (in Czech) was aimed at the presentation of common dust particles around us to young readers from the viewpoint of electron microscopy.
Award for talented PhD student
Simona Krmíčková, a PhD student employed with the Department of Geological Processes, has been awarded the Brno PhD Talent scholarship. In her dissertation, Simona Krmíčková focuses on the Sr–Nd–Pb–Hf radiogenic isotope study of magmatic rocks from the broader surroundings of Brno. On 28th February 2019, she received a symbolic cheque for CZK 300,000 from the hands of Markéta Vaňková, the mayor of the statutory city of Brno.
Dust particles investigation in the Meteor programme of the Czech Radio broadcast
Tomáš Hrstka, who is involved in the development of innovative automated electron scanning microscopy at the Institute of Geology CAS was invited to the Czech Radio to talk about the study of dust particles in the famous "Meteor" popular science broadcast. This interview was conducted within the popular science project Strategie AV21, Natural Hazards. Meteor o teleportaci, kojícím pavoukovi, sexu a písních kosmických; time 31:41 (Tracing dust particles).

2018 Outstanding Student Poster Award for Šárka Křížová
Ing. Šárka Křížová of the Department of Analytical Methods was awarded the 2018 Outstanding Student Poster Award at the International European Planetary Science Congress (EPSC 2018) held in Berlin on September 16–21, 2018. The award honored her results in the study of Australasian tektites.
Opportunities for Soil Sustainability in Europe
During November 2016, the Dutch Academy offered to lead an EASAC project on soils and organized a workshop for 20 pedology experts. This report has been recently submitted to the European Union as an obligatory document for a debate on soil sustainability. The project benefited from the work of its authors and reviewers of the Institute of Geology CAS (L. Lisá as a co-author and A. Žigová as one of the reviewers). The complete report of EASAC is available here. The document is free to distribute. The principal aim of EASAC is to unify the National Academies of Sciences of EU, Norway and Switzerland to provide scientific expertise to EU politicians. For additional information see here.
