orogenic cycles. The results of such correlations
also should be represented in a map and
discussed in two final volumes.
Summary of activities.
(a) Several circular letters were distributed,
containing messages, proposals, news, and recommendations
.
(b) The thematic meetings of small groups were
held, aiming at the discussion of particular problems.
Most of these meetings were organized
within the ambit of the activity of the International
Teams. Among these, there were a field
meeting in Hungary on the pre-Alpine geology of
the Sopron area, attended by some Hungarian
and Italian members; a meeting in Greece on
the pre-Alpine metamorphism in Greece, attended
by some Greek and Italian members; a meeting
in Rumania on correlation problems, attended
by some Bulgarian, Czechoslovak, Hungarian,
and Rumanian members.
(c) Exchange of visits, both within the ambit of
the training programme and the activity of the
International Teams. Specifically: Kleinschmidt
(West Germany), Kovac (Hungary), Petroni (Italy),
Tenchov (Bulgaria) visited Austria; Kovach
(Hungary), Sassi (Italy), Szederkenyi (Hungary)
visited CSSR; Petroni (Italy) visited Bulgaria;
Sassi and Szederkenyi visited CSSR; Boyer (Yugoslavia),
Sassi and Stojanov (Yugoslavia) visited
Greece; Sassi visited Hungary; Szederkenyi
visited Yugoslavia; Brime (Spain), Gomez
(Spain) and Lelkes (Hungary) visited Italy.
(d) The publication of the third volume of Newsletter,
to which 47 authors from 11 countries
contributed. The 25 papers published in this
volume represent a further contribution to the
coordinated synthesis of the numerous data produced
by the Project members.
(e) The Field Meeting 1981 organized by the
French and Spanish working groups was held in
France and Spain from 9-15 June 1981. The
scope of the meeting was a visit to the Western
and Central Pyrenees, the Montagne Noire, the
Eastern Pyrenees, and the Catalonian Coastal
Range. In addition to the field trips, two scientific
sessions and a business session also were
held. Sixty-four members of the Project from
13 different countries participated in this meeting.
(f) The meeting on Plutonism was organized by
the Italian Working Group jointly with the Societá
di Mineralogía e Petrologia. Some French and
Czechoslovak and numerous Italian geoscientists
participated.
(g) Numerous international collaborations were
active during 1981, generated within the ambit
of the Project: Austria-Italy (pre-Alpine metamorphisms
in Austria; Grobgneiss; palaeomagnetism);
Austria-CSSR (Palaeozoic volcanism
in Austria); CSSR-Hungary (Radiometric Geo-
16
chronology); CSSR-Hungary-Yugoslavia (Geotraverse
C); CSSR-Italy (pre-Alpine metamorphisms
in CSSR); Bulgaria-Greece (Biostratigraphy);
Greece-Yugoslavia (Pelagonian metamorphic
belt); Greece-Italy (pre-Alpine metamorphism
in Greece); France-Italy-Spain (Palaeogeographic,
structural and metamorphic Palaeozoic evolution
in Southern France and the Western Mediterranean
area).
The most important scientific achievements on
long-distance correlations are:
- the results represented in the sections, stratigraphic
columns and reports included in Newsletter
Volume 3;
- the outline of the pre-Alpine metamorphisms
in Greece, which is ready for printing; this
report will be added to the similar ones concerning
the pre-Alpine metamorphisms in
Hungary and Spain, which have already been
published.
One of the definite results of the Project refers to
the training and exchange of know-how among the
different national working groups. Taking into
consideration the heterogeneous scientific background
of the different groups, the large amount
of data exchange which we were able to carry out,
the internal reports, and the personal and smallgroup
meetings represented an important training
opportunity and an efficient way of bridging the
gaps for almost all Project members.
In addition, specific training programmes were
active during the year: (1) Conodont preparation
(Graz); (2) Heavy-mineral investigation (Graz);
(3) Palynology in low-grade metasediments (Sofia);
(4) Geopetrologic analysis of the crystalline basements
(Padova); and (5) Geobarometric classification
of low-grade metapelites (Padova). The
programmes were utilised by a few Project members
from other countries (7 in total, from 3 different
countries, for a total of 6 months).
Activities planned. The following main activities
have been planned for 1982, in addition to the many
others having more local interest:
- Field meeting in the Caucasus, to be organized
be the Soviet Working Group; during this field
meeting, some scientific workshops will be
held on the main correlation results, as well
as a business session;
- Some small-group meetings within the ambit of
the activity of the International Teams. These
meetings are necessary for elaborating the
most important interregional correlations,
formulating multidisciplinary models, integrating
the stratigraphie columns with the new results
on magmatism and metamorphism;
- Numerous visits, both within the ambit of the
training programmes and the activity of the
International Teams;
