In December 2015, research scientist Lukáš Ackerman was involved in the field work on carbonatites and associated alkaline rocks (phonolite, trachyte) in Middle India (localities Amba Dongar and Panwad-Kanwat) within the framework of research project of the Czech Geological Survey. These sites are located on the northernmost part of world known Deccan flood basalts erupted on the Cretaceous-Tertiary boundary. The collected samples will be for the first time analyzed for the concentrations of platinum-group element as well as osmium isotopic compositions in order to provide insights to carbonatite melt sources and possible role of parental melt crustal contamination.
Günther Kletetschka and his doctoral student published a paper on space weathering in the Icarus journal (Impact Factor: 3.038)
Laser irradiation of olivine as a proxy for micrometeorite impacts produced nanophase Fe0. This analog of space weathering was characterized by frequency-dependent susceptibility monitoring . Obtained data allow the modeling of space-weathering conditions in the environment of the Solar System.

Mercury environmental problem - Tomáš Navrátil and Jan Rohovec in the Czech Radio Plus –Leonardo Magazine
Mercury-containing thermometers were withdrawn from the market over six years ago. Amalgam dental fillings are on a retreat, nutrition experts warn against mercury-contaminated fish, and mercury was one of the main suspects in the case of Tycho de Brahe death. Is mercury really so dangerous? And what risk does it really pose for our health and for the environment? A view of geochemists is presented by Tereza Burianová.

The artistic and scientific project Frontiers of Solitude comes to its final phase: the main exhibition will take place in the Školská 28 Gallery, Prague, on 2nd February to 4th March 2015. Works created by Czech, Norwegian and Icelandic artists will reflect the landscapes of Iceland, northern Norway and northern Bohemia visited by the artists within three expeditions together with experts in Earth sciences, biology and ecology (Institute of Geology CAS was represented by Václav Cílek and Radek Mikuláš during the northern Bohemian expedition). An extensive catalogue will be published at the occasion of the exhibition in Czech and English.

Václav Cílek and Vojen Ložek are co-authors of two freely accessible publications:
Entering the landscape: on the nature and memory of central Bohemia (in Czech)
Central Bohemia : nature, man, landscape (in Czech)
Field excursion with students of the Evolution Secondary Grammar School in Prague took place on November 2, 2015. Its purpose was to investigate important geologic sections and fossil collection sites at Řeporyje (under the guidance of Radek Mikuláš).
The second year of the contest Photogenic Science marked the success of staff of the Institute of Geology of the CAS again. The first prize was awarded to Pavel Lisý for his rock art photo titled “I keep on burning”. Besides, photographs taken by Leona Chadimová and Lukáš Krmíček were selected for publication in a calendar to be used for the presentation of Czech science to partners of the Czech Academy of Sciences.
