A/ Projects with
project leaders from the Czech Republic:
Project #428 - Climate and Boreholes
Project Leaders: V. Cermak, H.N.
Pollack and C. Clauser
Czech Representatives: V. Cermak
(cermak@ig.cas.cz) and J. Safanda
Activities in 2004:
The project was O.E.T. in 2003. In 2004 no
activities directly related to the IGCP were organized and no report for UNESCO
was prepared. Unofficially it was agreed with Prof.Hugo Beltrami from the
St.Xavier University, Antigonish, NS Canada and Prof. R.N. Harris, Univ. of
Utah, Salt Lake City, USA that they would apply for a new similar IGCP project
formally to continue the previous topic.
Project # 469 - Variscan terrestrial
Biotas and Palaeoenvironments
Project leaders: C.J. Cleal (United
Kingdom), S. Oplustil (Czech Republic), Y. Tenchov (Bulgaria), E. Zodrow
(Canada)
Czech Representative: S. Oplustil

Activities in 2004:
Introduction
This project, which has been active for just
over one year, evolved out of an earlier collaboration (funded by the NATO
Science Programme) between palaeobotanists, palynologists and stratigraphers
from Canada, Bulgaria and the United Kingdom.
This project demonstrated the value of
collaborative work when trying to compare environments across the Variscan
Foreland, especially when using palaeontological data. The work showed that
there was a marked similarity in the vegetation changes that occurred across the
Foreland, with plant species apparently appearing and disappearing essentially
synchronously across wide geographical areas. This tended to suggest that
climate was a more important driving force behind these biotic changes, rather
than localized habitat-changes caused by factors such as variations in water
table. However, we had no evidence from terrestrial faunas and little from
sedimentology to provide a wider context for understanding our observations. In
the early phases of IGCP 469, we have therefore been attempting to expand the
work to include sedimentological and palaeozoological evidence, and to extend
it into the other Variscan coalfields of Europe and North America.
Activity of the Czech team
The second year of the project was
characterized by significant activities of the Czech WG (Dr. Jiri Bek, Dr.
Zbynek Simunek, Jana Drabkova MSc., Josef Psenicka MSc., Karel Martinek
MSc.,Milan Libertin MSc. and Richard Lojka MSc.).The members of the Czech team
focused on a revision of selected plant groups from the Late Palaeozoic
continental basins of the Czech Republic (S. Oplustil: lycophytes, Z. Simunek:
pteridosperms, J. Psenicka: ferns, M. Libertin: Sphenophytes). Contribution to
palynology was performed by J. Drabkova who studied miospore assemblages of the
upper part of the Nyrany Member. She identified rich association preserved in
siliciclastics, indicating Cantabrian age. Results of all the members of the
team were presented at Sofia (April) and Freiberg workshops and some of them
further prepared for publication in workshop volumes in the Acta Balcanica.
In October M. Libertin, J. Psenicka and S.
Oplustil visited Upper Silesia to sample youngest part of the coal-bearing
succession of the basin. S. Oplustil (in co-operation with C. Cleal) prepared a
tentative version of stratigraphic column for the Late Paleozoic continental
basins in central and western Bohemia. They also suggested criteria for which
kind of data will be required from each basin, which will serve as a base for
the open discussion and as an example.

Activities in 2004:
2004 was the first year of the project
characterized by the constitution of the Czech WG.
C/ Projects with
active working groups in the Czech Republic:
Project #449 – Global Correlation of
Late Cenozoic Fluvial Deposits
Project Leader: D. Bridgland (UK)
Czech Representatives: J. Tyracek,
P. Havlicek (havlicek@cgu.cz)
Activities in 2004:
2004 was the last year of the project. Broad
activities of the Czech team concentrated on two main topics in 2004. The first
studied the feasibility of stratigraphical correlation of the Moravian “main
terrace” defined in the realm of the Pleistocene continental glaciation in the
Ostrava basin and the “Hochterrasse” typical of the mountain glaciation in
Alps. The second was the study of discrepancies and affinities in the terrace
systems in both the stable Bohemian Massif and the mobile West Carpathians.
1) Main aim of the first study was better
understanding the geological structure of the main terrace, its dating and the
overlying sediments as well, and to determine the exact position of the
aggradation phase in the first order climatic cycle. The preliminary results
confirmed the validity of the Saale/Riss parallelisation as stated many times
in older literature. Both terraces belong to the same climatic cycle (Saale,
Riss), however, they differ in detail. The Moravian “main terrace” was aggraded
during the anaglacial (cooling) phase while the “Hochterrasse” correlates with
the kataglacial (warming) phase of the same glacial. In other words, the “main
terrace” correlates with the beginning and the “Hochterrasse” with the close of
the same glacial.
2) A specific development of river terraces is
typical of the Czech republic. The relatively narrow periglacial zone in the
Czech republic gripped between the Scandinavian ice sheet and a large Alpine
ice cap had never been glaciated. And because no other powerful erosion agent
intervened, the river valleys should theoretically preserve complete
undisturbed record of the entire period of terracing. The preserved terrace
sequences demonstrate such a development. In the long stable Bohemian Massif 11
to 15 step-like terraces, classified into high, middle and low terrace groups
are developed and sufficiently documented. Regular development of terrace
systems indicates relative tectonic stability or positive movement of the
massif as a whole.
In contrast two large alluvial fans instead of
the high terraces group are developed in geologically younger and tectonically
unstable Moravia (West Carpathians). Complex geological structures were
identified in both fans. Both of them are composed of several gravel
accumulations separated by intervening fossil soils evidencing long hiatuses of
interglacial type. Lower terraces incised deeper below the level of fans show
regular development similar to that in the Bohemian Massif. They evidence the
termination of tectonic movements and beginning of subsequent tectonic
stability staring probably at the beginning of Middle Pleistocene.
In the framework of the bilateral cooperation
between the Slovak and Czech Geological Surveys a field excursion was realized
in September 2004. Main objective was a study of fluvial sediments in both Vah
and Morava river valleys, dating the terraces and mutual correlation. The
results are supposed to be used respectively for interregional correlation in
the IGCP 449 final report and for the tectonic studies in the follow-up
project.
Starting in 2005 the Czech team will participate
in the follow-up project if approved.

Project #454 - Medical Geology
Project Leaders: O. Selinus and P.
Bobrowsky
Czech Representative: J. Mrnkova
(mrnkova@cgu.cz )
Activities in 2004:
In 2004 Czech activities were very limited, as
our major grant proposal submitted to the Czech Grant Agency was not approved.
As a result of this situation we try to push through the administration of the
Czech Geological Survey another new project on similar topic. The main goal of
this project is to gather information about the biogeochemical distribution of
arsenic in the environment near selected areas of long-lasting mining
activities (Kutna Hora district) and in an area without similar activity
(Benesov district). Another task is to investigate possible connection between occurrences
of arsenic and certain types of human diseases. Comparison of the areas with
old mining load and the areas without contamination will be included in the
project. Medical specialists will be involved in this part of the study. The
first stage of the project will include desk study of the geochemical and
medical data and searching for the correlation between the geological base of
the environment and health condition of its inhabitants. The second stage will
include sampling in places where contamination is expected. The selected sample
media are: surface water and soils.
Project #463 - Upper Cretaceous
Marine Red Beds
Project Leaders: C. Wang, M. Sarti,
R.W. Scott and L.F. Jansa
Czech Representative: L. Svabenicka
(svab@cgu.cz)
Activities in 2004:
The objective of the project is to establish
the causes of major change in the world ocean basins from deposition of organic
carbon-enriched sediments to oxic, red beds.
Institutions co-operating in project IGCP No.
463: Czech Geological Survey (Miroslav Bubik and Lilian Svabenicka), Institute
of Geology, Academy of Sciences of the Czech Republic (Marcela Svobodova) and
Institute of Geological Engineering, VSB – Technical University Ostrava (Petr
Skupien and Zdenìk Vasicek).
In 2004 research focused on the organic
(microfossil) content and integrated stratigraphy of the initial oxic deposits,
oceanic red beds in the Outer Western Carpathians (Moravia, Czech Republic).
Section containing intercalations of red calcareous claystone in the Middle
Subbetic (Southern Spain) was studied in cooperation with Prof. Massimo Sarti
(Italy) and Dr. Xiumian Hu (China). Results were presented at workshop in
Bucarest, Romania (August 15-19, 2004) and at the 32nd IGC in Florence, Italy
(August 23-27, 2004).
- According to our preliminary data
(microfossil content – foraminifers, dinocysts and calcareous nannofossils),
change in the deposition from Corg – rich black shales into red beds avoid of
any carbon occurred within the Upper Cenomanian interval.
- The foraminiferal fauna of the Cretaceous
oceanic red beds deposited below the CCD was studied in 300 m thick section of
Bystra Potok (Silesian Unit, Outer Flysch Carpathians). Foraminiferal data were
compared with the dinocyst biostratigraphy. The most interesting new observation
was the early occurrence of Uvigerinammina jankoi (from Cenomanian) as well as
some other marker taxa (Rzehakina minima, Caudammina gigantea).
- Biostratigraphy (calcareous nannofossils) of
„red beds“ and other sediments demonstrated during the IGCP 463 excursion in
Bartin, Turkey 2003 was elaborated and sent to Prof. Okan Tuyuz to Istanbul.
- Database (coordinator Robert W. Scott, USA)
of the Upper Cretaceous “red bed” sections on the territory of the Czech
Republic has been prepared.

Project # 471 - Evolution of Western
Gondwana during the Late Palaeozoic
Project leaders: C.O. Limarino and
L.A. Buaotois
Czech Representative: R. Mikulas
(mikulas@gli.cas.cz)
Activities in 2004:
2004 was the third year of the project. The
Czech activities focused on the trace fossil records in basin fills of closing
Gondwana-Laurussia oceans are described in the following text prepared by Radek
Mikulas, Ondrej Babek, Tomas Lehotsky and Jan Zapletal. The Lower Carboniferous
Moravian-Silesian Culm Basin (MSCB) represents the easternmost part of the
Rhenohercynian system of collision-related, deep-water foreland basins (Culm
facies). The Upper Visean Moravice Formation (MF) of the MSCB shows a distinct
cyclic stratigraphic arrangement. Two major asymmetric megacycles bounded by
basal sequence boundary, each about 500 to 900m thick, have been revealed. The
megacycles start with 50-to-250 m thick, basal segments of erosive
channels-overbank successions and slope apron deposits interpreted as lowstand
turbidite systems. Up-section they pass into hundred metre-scale thick,
fine-grained, low-efficiency turbidite systems. Paleocurrent data show two
prominent directions, basin axis-parallel, SSW-NNE directions, which are
abundant in the whole MF, and basin axis-perpendicular to oblique, W-E to NW-SE
directions, which tend to be confined to the basal parts of the megacycles or
channel-lobe transition systems in their upper parts. Based on the facies
characteristics, paleocurrent data, sandstone composition data and trace-fossil
distribution data we suggest a combined tectonics-sediment supply driven model
for the MF basin fill. Periods of increased tectonic activity resulted in slope
oversteepening probably combined with increased rate of lateral, W-E sediment
supply into the basin, producing the basal sequence boundary and the subsequent
lowstand turbidite systems. During subsequent periods of tectonic quiescence
the system was filled mainly from a distant southern point source, producing
the thick, low-efficiency turbidite systems. Consistently with the previous
models, our own sediment composition data indicate a progressively increasing
sediment input from high-grade metamorphic and magmatic sources up-section,
most probably related to an uplift in the source area and progressive unroofing
of its structurally deeper crustal parts. The first occurrence of the Cruziana-Nereites
ichnofacies in sand-rich turbidite systems in the youngest parts of the MF
(Goβel to Goβspi Zone), supported by rapidly increasing quartz
concentrations in sandstones, is thought to indicate a transition from
generally underfilled to generally overfilled phase in evolution of the MSCB
basin. This transition may be linked to the onset of Upper Visean phase of
northward basin-fill progradation assumed by previous authors.
In 2005 research interest will be focused on
the study of trace fossils from the easter part of the Culm facies in Moravia
(Czech Republic).

Project # 479 – Sustainable Use of
Platinum Group Elements
Project leaders: J. Mungall, M.
Iljina, C. Ferreira-Filho
Czech Correspondent: I. Knesl
(knesl@cgu.cz)
Activities in 2004:
Czech participants decided to join IGCP 479
only recently. Project representative was in touch with Dr. Mungal regarding a
possible Czech contribution to this project. It was suggested that the Czech
team, which includes participants from the Czech Geological Survey and Faculty
of Science (Charles University) in Prague, would add missing info on PGE
occurrences in Czech Republic to the project’s database. New research
activities focused on the verification of some “older” PGE localities
especially in the Lusatian area is planned for 2005. Czech participants plan to
take part in the meeting of the project in Oulu, Finland (2005).
Project # 486 -
Au-Ag-Telluride-Selenide Deposits
Project leaders: N.J. Cook (Norway),
K.Kojonen (Finland)
Czech Representative: A. Vymazalova
(anvym@cgu.cz)
Activities in 2004:
The project is a vehicle for scientists working
on the processes involved in the genesis of tellurium and selenium-enriched
Au-(Ag) deposits , who wish to correlate, compare and contrast their
observations and conclusions. Objective of the project is to encourage
interaction between ore mineralogists and geologists, as well as ore fluid
geochemists, experimentalists and persons working on theoretical aspects,
whether at the ore field, mine, or microscopic scales.
The activities of the Czech WG (Anna Vymazalova
and Milan Drabek from Czech Geological Survey and Jiri Litochleb from the
National Muzeum) were focused on experimental studies. Phase relations in the
Pd-Sn-Te system, the ranges of solid solutions, and structural properties of
Pd-Te and Pd-Sn phases were studied. Experimental works were also focused on
synthesis of tellurides under hydrothermal conditions and to obtain single
crystals for crystal structure determination.
The results were presented at the Geological
Congress held in Florence, Italy (August 20-28) and at a workshop in Alba
Iulia, Rumania (August 30th - September 7th, 2003).

Project 491 - Middle Palaeozoic
Vertebrate Biogeography, Palaeogeography and Climate
Project leaders: M. Zhu (P.R.
China), G. Young (Australia)
Czech Representative: J. Zajic
(zajic@gli.cas.cz )
Activities in 2004:
2004 was the second year of the project,
characterized by significant activities of the Czech WG. Summaries of selected
non-marine Upper Carboniferous (Moscovian-Gzhelian) – Lower Permian
(Asselian-Sakmarian) aquatic vertebrates (hybodontid sharks, acanthodians, and
actinopterygians) in the Bohemian Massif were done. The results concerning
acanthodians and actinopterygians were presented by Stanislav Stamberg
(personally) and by Jaroslav Zajic (only through submitted abstract) in the
10th International Symposium on Early/Lower vertebrates, Gramado, Brazil. The
summary on hybodonts was presented by Jaroslav Zajic at the 10th Coal Geology
Conference, Prague.
New biostratigraphy was proposed for the
Boskovice Basin in Bohemian Massif.
The local biozones based on non-marine aquatic
vertebrates of the Bohemian Massif were supplemented. The Upper Stephanian
Sphaerolepis-Watsonichthys biozone was renamed for Sphaerolepis-Elonichthys.
The lower Watsonichthys subzone was adequately renamed for Elonichthys subzone.
The upper boundary of the Lower Sakmarian Xenacanthus decheni biozone was
shifted to a higher position due to new shark findings in the Krkonose Piedmont
and Intra-Sudetic Basins. The Asselian Lower Letovice Formation (Boskovice
Basin) yielded special vertebrate association of the upper Acanthodes gracilis
biozone, not known from the other basins yet.
The compilation of database on „Acanthodians of
the World“ is in progress. The initial „Acanthodian web“ is ready to be
launched.

Activities in 2004:
As a part of activities of this IGCP Project a
Czech regional working group has been established in the year of the project,
with O. Fatka as a leader. It includes the following institutions: Charles
University Prague (Doc. RNDr. O. Fatka, CSc. – organic-walled microfossils,
Doc. RNDr. J. Marek, CSc. – cephalopods, Doc. RNDr. K. Holcova, CSc. –
foraminifers, Mgr. S. Berkyova – tentaculites, Mgr. M. Valent – hyolithids)
Academy of Science Prague: (Doc. RNDr. J. Hladil, DSc. – stratigraphy, corals,
RNDr. J. Slavik, Dr. – conodonts), Czech Geological Survey Prague: (RNDr. P.
Budil, Dr. – trilobites, RNDr. J. Fryda, Dr. – gastropods), Masaryk University
Brno: (Prof. RNDr. J. Kalvoda, CSc. – stratigraphy, foraminifers), National
Museum Prague: (RNDr. R. Prokop, CSc. – echinoderms).
The first meeting of the regional team is
planed in the form of a special session on the Fifth Czech-Slovak-Polish
Palaeontological Seminar in Olomouc in 2005.
Project 502 – Global comparison of
volcanic-hosted massive sulphide districts: the controls on distribution and
timing of VMS deposits.
Project Leaders: R. Allen (Sweden),
F. Tornos (Spain), J. Peter (Canada), N. Cagatay (Turkey)
Czech Correspondent: J. Pasava
(pasava@cgu.cz)
2004 was the first year of the project. This
project aims to compare a number of the world’s important VMS districts in
order to define the key geological events that control the distribution and
timing of high-value VMS deposits; and thereby develop new criteria for
locating these ore deposits. Czech contribution (Jan Pasava and Anna Vymazalova
from the Czech Geological Survey) was through the study of the distribution of
PGE in massive sulfides from active hydrothermal field, eastern Manus basin,
Papua New Guinea. This study enabled to explain PGE enrichment in some ancient
volcanogenic massive sulfide deposits. A field trip to IPB (Spain) for project
participants is planned for April 2005.

Activities in 2004:
2004 was the first year of the project
characterized by the constituion of the Czech WG and already rather broad
scientific activities. Five contributions by Czech palaeontologists and
stratigraphers were presented on the first meeting of this IGCP in Erlangen
(Germany) in September 2004. It was agreed to organize a special session of
this project during the C.I.M.P. Meeting in Prague in 2006.
4. IGCP meetings held
in the Czech Republic in 2004

6. Other relevant
information
The Czech IGCP National Committee was one of organizers
of the GEOCHIM 2004 - a postgraduate training course on Geochemical Exploration
Methods and their Environmental Applications. This certificated course took
part in Prague and Dolni Rozinka between September 6-20, 2004 and 15 scientists
representing 12 - mostly developing countries participated in this event.
In order to promote IGCP activities in the
Czech Republic the Committee has also continued in seeking funds for the IGCP
National Committee special foundation established in 1996. Generous donations,
which enabled to offer 8 grants in the total amount of 80 000.- Czk was kindly
provided by a major sponsor of the Czech
IGCP National Committee: Severoceske doly, a.s. (SD a.s., Chomutov), and also
by Galahad Investment, s.r.o. (Kladno) and GeoTec – GS, a.s. (Praha)
