A new style of sandstone disintegration documented
A recent paper in Geomorphology was also contributed by Michal Filippi of the Institute of Geology. It presents a newly recognized weathering style of sandstone outcrops. Its essence lies in a disconnection of smaller parts of rock along lithological and other discontinuities, which allows the material to dilate and damage the protective bio-crust on the cliff face. This results in a more effective function of erosion factors in the disconnected parts and their accelerated disintegration.
The Deanʾs Award
Hedvika Weinerová was awarded the Deanʾs Award for best students in the Doctoral programme for the year 2021. Her study at the Faculty of Science of Masaryk University is focused on changes in the composition of carbonate sediments of the Barrandian area with respect to Devonian bioevents and sea-level changes.

Progress in the study of cadmium
Cadmium (Cd) is a toxic metal widely occurring in the environment, often due to the human activity. The employees of the Institute of Geology of the Czech Acad Sci have developed a method for measuring Cd isotopes in biological samples using thermal ionization mass spectroscopy (TIMS). The results published in the prestigious analytical journal Talanta represent a useful tool in the quality control of chemical analyses for all laboratories involved in the analysis of cadmium in biogenic materials.

The oldest trilobites had babies with large heads and long spines
Trilobites are the most iconic inhabitants of the Paleozoic seas. These arthropods possess an exoskeleton that was hardened by calcium carbonate shortly after they hatched from the egg. Owing to this fact, their developmental stages are often preserved in the fossil record. In their new paper, Lukáš Laibl with his colleagues from Freie Universität Berlin described the development of trilobite Fritzolenellus lapworthi from Cambrian strata of Newfoundland, from tiny individuals smaller than one millimeter up to the nearly 20 cm long adults. Juveniles of Fritzolenellus show a large cephalon and distinct spines on their body. Based on a detailed comparison of Fritzolenellus babies with those of other Cambrian trilobites, the authors showed that features seen in Fritzolenellus have the original morphology inherited from the last common ancestor and can be thus used as a reference group when studying the ontogeny of other trilobites.

Promotion of geosciences: a new open-air rock exhibition
On the occasion of the International Day of Museums and Galleries, a new outdoor geological exposition "Selected Rocks of the Rakovník District" will be opened on Tuesday, May 18, 2021 from 4 pm near the Museum T.G.M. in Rakovník. A number of subjects participated in the preparation of the exhibition, including the Institute of Geology represented by Karel Žák and Jiří Adamovič. This exhibition is one of many examples of the outreach of scientists-geologists beyond the area of "hard science" in conveying their knowledge to the general public. Those interested can visit the exhibition free of charge during the museum's opening hours.
Institute in the Database of Transfer, Knowledge and Technology of the Czech Academy of Sciences
Institute of Geology has been involved (through several topics) in a recently established database, which aims at "connecting science with business". In other words, this database offers useful results, products and procedures, as well as research facilities, methodologies, analyses and other knowledge that people from commerce, research and education, as well as the general public, may wish to use.
Lesní potok catchment – presentation
Short 5 minute presentation including overview of Lesní potok catchment instrumentation and selected scientific achievements was given by Tomáš Navrátil in framework of “2021 Winter Cyberseminar Series: Research and Observatory Catchments: the Legacy and the Future” organized by CUAHSI (The Consortium of Universities for the Advancement of Hydrologic Science, Inc.). Follow this link to watch the Week 5 Section entitled “Low to no Snow Temperate Catchments”. The main purpose of this event was to bring the wide audience of catchment related research scientists familiar with location, instrumentation and/or results of others. The schedule and recordings of all presentations can be found here.
Introduction to the Institute
An informative brochure titled “INTRODUCTION to the Institute of Geology”, which provides comprehensive information about the Institute structure, equipment and activities, was updated and presented on our webpage. It is a good springboard for those who are seriously interested in scientific work in the field of geology and in events at the Institute of Geology.
Book award
The book “Underground monuments of central Bohemia” by V. Cílek (Institute of Geology), M. Majer, L. Faltejsek and others, published by the Dokořán publisher in 2019, was awarded – after several postponements – the Egon Erwin Kisch Prize for non-fiction literature for the year 2020. The book describes underground spaces of various types in central Bohemia, concentrating on remains after ore, coal and limestone mining. The wide distribution of historical mines documents and explains the rapid, multi-level boom of central Bohemia. Many congratulations to the authors!
