Florence, Italy

23 August 2004

The meeting was attended by the following persons: C. Gillen (Great Britain); I. Kukkonen (Finland); D. Ohnenstetter, J. Ludden, S. Zolotikova (France); H. Kern, R. Borchardt, U. Harms (Germany); J. Trckova (Czech Republic); F. Gorbatsevich, T. Bayanova, V. Il'chenko, Yu. Yakovlev (Russia).

Co-ordinator C. Gillen asked the present group leaders to make brief presentations on work plans

and ask him questions if they have any.

D. Ohnenstetter. The project tasks set for the French group are being fulfilled. An article has been prepared, it is in print now. More than 10 ICP-MS analyses have been made. The analysis of geochronological data for Pilgujarvi massif is being continued together with T. Bayanova (Apatity).

H. Kern informed that a comparison of the KTB and SG-3 sample properties is being carried out by neutron diffraction. The findings of this investigation can be used in the INTAS report.

J. Trckova. By now the tests on six SG-3 deep and surface samples have been completed. A great variety of techniques have been used for the tests. Velocity characteristics, elasticity and strain moduli, Poisson's ratio and rock strength indexes have been determined. Deep and surface rock samples differ in these characteristics. A scientific paper has been prepared and is in print now. Petrographic determinations and permeability measurements are being carried out together with K. Lobanov and A. Zharikov from Moscow (Russia). At present we have got rock samples from Zapolyarny and Moscow.

R. Borchardt. Detailed measurements of 15 deep rock samples have been performed. Reports on the fulfilled analyses have been sent to the Apatity and Zapolyarny research teams. We have some questions on the sampling depth and rock types. To complete the work we shall need 5 more samples. The samples should have vein cracks intersecting schistosity, they must be composed of banded and layered rocks.

Yu. Yakovlev. In 2003-2004 we carried out monitoring of fluid dynamics, temperature field parameters, measured microseismic noises etc. in SG-3. We continued the work on documenting the core and its mineralogical, petrographical and petrological description. Determinations of ore minerals were carried out. The core samples and geological, geophysical etc. documentation were transmitted to other teams working for the project.

T. Bayanova. We continue marking the Kola Superdeep Borehole section. Rocks from different depths are being dated. The structure of the rock mass intersected by the borehole will be refined by these age marks.

I. Kukkonen. We continue analysing heat generation in the SG-3 section. We plan to perform fission-track analyses, but we have not got the proper apatite grains to fulfil this task. D. Ohnenstetter and T. Bayanova promised to convey the isolated apatite grains to I. Kukkonen for this purpose.

S. Zolotikova. There are some difficulties in creating the project web page. As has been mentioned before, this page should have an individual address. It may contain both open information accessible to everybody and closed one to enter which you must give the password. The problem is where this page can be placed. F. Gorbatsevich said he can clarify this issue in Apatity.

U. Harms. The results and information obtained at the Kola Superdeep Borehole still attract great attention. We still get requests to convey the data and samples from SG-3 for investigations.

J. Ludden suggested that the project participants prepare the resulting papers for the first General Assembly of EUG to be held on 25-30 April 2005 in Vienna, Austria.

F. Gorbatsevich. We continue determining physical properties of rocks. Particular attention has been given to the study of elastic and structural anisotropy parameters as indexes that are closely related to tectonics and palaeostresses in the borehole section. The processed and analysed data on the rock elastic anisotropy, assessment of palaeo- and modern stresses in the SG-3 section are described under properties, texture and state of rocks in the Kola Superdeep Borehole section that will be in the book "Lithosphere of the Russian part of the Baltic Shield" which is being prepared. According to the information from the Yekaterinburg team, at the end of 2003 an additional volume of investigations on microseismic noises in SG-3 in the range of 300-6840 m has been done. The spectral analysis showed that in some intervals the noise characteristics are similar to those that appear at the gas emission in the borehole. Mineralogical and magnetometric determinations of the core samples are being performed

Co-ordinator C. Gillen noted that the report on the project for the second year received a high appraisal. The information from the team leaders is evidence of the lack of the project-related problems. But it is greatly desirable that the web page elucidating the main achievements of the project should be created, since this obligation was undertaken. C. Gillen is going to apply for the project continuation. But he is not sure that this continuation will be supported financially. New ideas and approaches are wanted. The final report forms differ from the annual ones.

These forms should be filled and sent to C. Gillen by the 31-st April 2005 at latest. In the report, as well as in the papers that are being prepared for publication, particular emphasis should be placed upon the reflection of mutual co-operation between West-East and East-West. It may be implemented in mutual publications of investigation results. Of great importance will be the papers in international journals, such as Tectonophysics, Precambrian Research etc. People should note our project number in the papers - INTAS-01-0314. The Russian teams' leaders should send their reports to F. Gorbatsevich and the leaders of western teams - to C. Gillen.

In conclusion I. Kukkonen informed the meeting participants on the deep research borehole drilling project in the Outokumpu deposit area, Finland. To date the Russian concern "Nedra" has drilled this borehole down to a depth of 1.5 km. The final depth will be 2.5 km. The core is being taken along the entire section. The completion of drilling has been set for the end of 2004. The age of rocks is Early Proterozoic. The major part of investigation on the core and borehole will be carried out by the Finnish Geological Survey, but it plans to attract foreign specialists as well. I. Kukkonen suggested that the participants visit the project web-site http://www.gsf.fi/projects/o_k_deepdrilling/index.htm and prepare their proposals for participating in the project.

The exchange of participants' views resulted in arriving at a decision to hold the closing meeting of the INTAS-01-0314 project during the General Assembly of EUGS on 25-30 April 2005 in Vienna, Austria.

After that the meeting was closed.
