EUROPROBE Workshops
URALIDES and SW-IBERIA WORKSHOP
Report of the meeting in Granada, 23 - 29 March,
1996
The Granada workshop,
covering Palaeozoic orogen processes and involving the two EUROPROBE projects URALIDES and
IBERIA, was attended by 121 scientists from 17 countries, including 38 from Russia and
non-ESF countries (see Annex 1). The programme (Annex 2) was divided into three parts, the
first concerning the URALIDES (23-25th), the second IBERIA (26-27th) and the third, an
excursion to the southwestern Iberian Variscides (28-29th).
The URALIDES programme
concentrated on presenting results of last year's very active field season. 31
presentations gave an overview over the actual state of data acquisition and
interpretation. The meeting started with four presentations of the spectacular URSEIS
data, followed by seismic data from the middle Urals. Thereafter the progamme concerned
the results of ongoing Europrobe research, including interpretation of the seismics,
discussions of the plate-tectonic framework of Uralian orogeny, investigations of
ophiolite emplacements and thermotectonic histories, magmatic processes and mineralogy and
petrology of ore deposits, etc.. The largest western European national group (from
Germany) presented their ongoing and planned investigations in the Urals with a particular
emphasis on the recent development of the DFG special programme for the URALIDES, a direct
result of EUROPROBE's URSEIS experiment. Several invited speakers (Puchkov, Chemenda,
Matte, Bea, Windley) presented overviews on different topics related to the evolution of
mountain belts with especial reference to the Uralides.
The results of this
workshop will be published in an special issue of Tectonophysics (1997, v.
276, Nos. 1-4, Edited by Pérez-Estaún, Brown and Gee).
Since most of the
IBERIA subprojects are still in their preparatory phase, the second part of the programme
consisted mainly of overview presentations of the Iberian Variscides and their position in
the Variscan orogen (first day) and presentations (Annex 3) of the actual status of every
subproject (second day). During the afternoon of the second day, the different groups met
in order to establish partnerships (some new) and define common interests. During these
meetings, an increasing interest of western and eastern European scientists in the
different subprojects was recognized which was one of the major goals of this part of the
workshop. In order to improve the future organization of the IBERIA project, the
scientific leadership of Antonio Ribeiro
(Lisbon) will be supported by an organizational secretariate in Granada, with Antonio Azor
and Fernando Bea responsible.
The last two days of
this workshop were devoted to a field excursion (lead by Antonio Azor) in the Spanish part
of the project area (Annex 4). The focus was on the field evidence for transpressional
deformation, promoting a discussion of the results that may be obtained by geophysical
studies of the whole lithosphere across the transpression zone.
A revised draft of the
IBERIA part of the EUROPROBE Brochure was presented at the meeting and is being reworked.
We thank the local
organizers, especially Prof. F. Bea (Granada University) and T. Solans (CSIC) for
preparing and running the meeting. The meeting was partly sponsored by CICYT, Junta de
Andalucia, University of Granada and ENRESA.
