Introduction
This year, 2015, differs from some of preceding ones. Not only by extraordinary
warm and dry weather, which is expected as a consequence of the global warming
due to human activities according to some persons. Nevertheless, green-house pe-
riods during Paleozoic, Mesozoic and Tertiary were substantially warmer than re-
cent climate and without human impact, as well as some of Pleistocene interglacials.
Clearly we are facing the end of interglacial period characterized in the geologi-
cal past by abrupt climate changes, sudden jumps in temperatures and other events.
More, the geomagnetic field has been substantially weakening in last years, indica-
tion of approaching change of polarity of Earth magnetic field? But to return to our
topics: similar hot climate was also within the Institute itself. The institute person-
nel were very busy by the preparation of the cyclic evaluation of all institutes of the
Czech Academy of Sciences according to new unified methodology prepared by the
Academy management and approved by the General Assembly of the Academy. As
usually, great amount of paper was used for documentation of our activities in 2010
to 2014, although most of data were available electronically, economic data even
on-line. The whole evaluation passed in two periods, in the first one Institute depart-
ments had to decide on selection of extraordinary published outputs. Selected papers,
mostly peer-reviewed, were reviewed again by 2 independent reviewers from over
the whole world, and special commission was established for each evaluated science
branch. The second period represented the evaluation of departments and Institute
activities and was summarized by the visit of the Evaluation Commission at the be-
ginning of November. Now, preliminary results are available, and it seems that the
evaluation resulted highly positively, lets only to hope, that good evaluation results
will be reflected in better financing on the Institute by institutional sources from Academy chapter in the state budget.
Except above mentioned exercises, the life in the Institute passed quite smoothly. I have to mention also some good results and
successes. The Institute staff was highly successful in the Grant Agency of the Czech Republic (Czech Science Foundation), we ob-
tained altogether 7 grant projects with the start in January 2016! Our personnel was also successful in obtaining different kinds of fel-
lowships, Dr. Jiří Sláma, returning from University of Bergen, Norway, after several years, obtained prestigious Purkyně Fellowship
donated by the Czech Academy of Sciences for 2016–2020, sponsored by nice financial sum not only for research. The investment
money to renewal of the laser ablation equipment of our ICP-MS in amount of about 6 mio CZK are linked to this fellowship; the in-
vestment was obtained in annual tender organized by the Academy. Dr. Filip Tomek was successful in competition for Post-doctoral
Fellowship also established by the Czech Academy of Sciences.
Except the Institute evaluation, we realized the cyclic evaluation of whole scientific staff for period of 2012 to 2014 important for
evaluation of personnel productivity and for planning of human sources in near future. The tender for new positions was also success-
ful, number of external young scientists attended again. Three of them will be accepted from February 2016 to strengthen the Depart-
ment of Paleobiology and Paleoecology. In spite of such time-consuming activities, the publication output of the Institute personnel
remained at similar level as during past years (see Chapter 5a), and lot of papers were submitted during 2015, number of them waiting
for early print in 2016. The Institute was also visited by number top geoscientists, some spending their sabbatical here. International
cooperation in research and development of new methods continued successfully and intensively. Popular science, especially in the
frame of complex Academic project Strategy 21, has been developing explosively.

(USA): The chemical research of glass objects from Salma’s
Palace in Prague (Š. Jonášová; 2015)
The work was focused on the archaeometric survey of el-
egant and ordinary glass materials from the archeological re-
search of Salm’s Palace in Prague. These glasses were found
in a cesspit. The glass finds are well documented, however less
is known about their chemical composition and the production
technology. The aim of the project was to determine chemical
composition of these glasses and help to understand the details
of their manufacturing. The chemical analysis of glass samples
mostly proved a composition of potassium-calcium glass and
therefore points to domestic origin. Only small part of analyzed
glass samples was made from sodium-calcium glass.

The Malužinská Cave is located on the right side of the
Bocianka Valley (Nízke Tatry Mts., northern Slovakia). By its
nature and position, it represents one of the most important ca-
ves in the area. It is developed in Middle Triassic Gutenstein
limestones, dolomites and breccias of the Choč Nappe. It was
expected, that the cave was formed by dissolution by seeping
meteoric rain- and melt-waters or by underground waters from
sinking allochthonous Bocianka Stream. The origin of prima-
ry solution halls and passages with numerous blind chimneys,
ceiling pockets and cupola-shaped cavities was controlled by
steep faults of NW–SE, NE–SW, N–S and E–W directions. In
some cave segments, original phreatic morphologies were re-
modelled by breakdowns along intensively faulted bedrock, ma-
inly along intersections of faults with different directions and
inclinations. In addition to breakdown products, only fine-grai-
ned allothonous sediments (yellowish-brown clay) occur in the
cave. Allochthonous gravels and sands are completely absent
here, in spite of aggraded fluvial fill in nearby surface Bocianka
riverbed. The resurgence of gently warmed waters is located at
the Malužiná Village just below the cave. The original soluti-
on morphologies in the cave serve as clear indicator of phreatic
