The Radek Melka Prize for the best paper of the CETeG 2015 Conference awarded to Filip Tomek

     At the 13th Meeting of the Central European Tectonic Groups (CeTeG), Filip Tomek received
     the Radek Melka Prize for his paper “Magma flow paths and strain patterns in magma chambers
     growing by floor subsidence: a model based on magnetic fabric study of shallow-level plutons in
     the Štiavnica volcano–plutonic complex, Western Carpathians” published in the Bulletin of
     Volcanology last year. Filip Tomek is a PhD. student working for the Institute of Geology of the
     CAS. This study revealed complex magma flow patterns and mechanisms of magma chamber
     construction on the example of the Štiavnica stratovolcano, Western Carpathians.

A new species of calciphilous Cortinarius from the Czech Karst

The number of species of macrofungi in Central Europe is estimated to a several thousands. Despite the intensive work of European mycologists in the last decades, new macrofungal species are still being described from Europe. The occurrence of many species is influenced by geological bedrock. Macrofungi are not restricted to specific rocks but prefer basic or acid soils derived from various types of rocks. This relationship is one of the areas studied by the scientific discipline called geomycology.

Cryogenic cave carbonates – a new tool to estimate the minimum permafrost depth of the Last Glacial

Cryogenic cave carbonates can be identified in caves based on their characteristic mode of occurrence, typical shape, unique carbon and oxygen stable isotope compositions, and based on ages confirming their formation during the Glacial. Low-ventilation caves generally show temperature close to those of the surrounding rock. Cooling of such caves to freezing and/or subfreezing temperature is possible only due to evolution of permafrost (permafrost is the zone of soils and rocks having temperature 0 °C or lower for at least two subsequent years).

Ichnofossils associated with slightly skeletonized body fossils, Middle Cambrian of the Barrandian area, Czech Republic

Sediments of the Middle Cambrian of the Barrandian area yielded several distinct morphotypes of ichnofossils preserved in a tight association with non- or slightly-mineralized animal body fossils, most often arthropods. These traces, in lesser diversity, were described from the Cambrian of the Barrandian area already in 2000 by the present author. Later, since 2006, analogous trace fossils have been described from classical Cambrian lagerstätten, namely Chengjiang and Burgess.

Mineral inclusions in placer zircon from the Ohře (Eger) Graben: New data on „strontiopyrochlore“

After qualitative examination of the inclusion inventory of 80 zircon megacrysts from alluvial placers of the Cenozoic alkali basalt area of northern Bohemia and southeastern Saxony, three representative megacrysts from the Podsedice deposit were selected for an in-depth study of inclusion minerals. Primary and secondary inclusions were distinguished and used as monitor for zircon-related syn- and epigenetic processes.

Kozlowskii Event: mass faunal extinction and global environmental perturbations recorded in the upper Silurian succession of the Prague Synform

Upper Silurian sedimentary succession of the Prague Synform preserved particularly complete record of prominent global biotic crisis, known as Kozlowskii or Lau Event, as well as subsequent recovery of the marine biota. The most affected among pelagic faunas were planktonic graptolites. Almost simultaneous, selective extinction of several little phylogenetically related and greatly specialized taxa was recorded at the top of the kozlowskii Biozone.

About Institute

SuchdolInstitute of Geology AS CR, v. v. i. is a medium-sized research center which main purpose is to gain, interpret and integrate the knowledge of the Earth System and its geologic and biologic past, without which it would not be possible to understand the recent environment. The Earth system understood as a result of interaction of endogenous and exogenous geological processes, development of biota and anthropogenic effects. Co-evolution of the Earth system means close connection and constant mutual influence of biotic and abiotic processes resulting in changes of atmosphere composition, climatic changes and weathering rates, relief development, sedimentary basin development and genesis of some types of natural resource bearings.
