PASSEQ:
PASSEQ 2006-2007

Passive Seismic Experiment in TESZ.

Participating countries:

Austria, Czech Republic, Denmark,Finland, Germany, Hungary, Lithuania, Poland, UK, USA

COORDINATION: M. Wilde-Pi´orko, mwilde@igf.fuw.edu.pl

PASSEQ will mainly concentrate on the Trans-European Suture Zone (TESZ) in the transition between Proterozoic and Phanerozoic Europe. The main aim of the PASSEQ is an investigation of the seismic structure of the mantle in TESZ in Central Europe, between young Palaeozoic platform of the Western Europe and much older Precambrian East European platform. The knowledge of deep structure of the TESZ is very important for understanding the tectonic processes in Europe. Thanks to very good knowledge of seismic structure of the crust from deep seismic sounding experiments: POLONAISE97, CELEBRATION 2000 and SUDETES 2003, it is possible to make very good crustal corrections which are necessary for mantle investigations.

The main target of PASSEQ is an investigation the structure of the upper mantle, particulary:

structure of lower lithosphere,

lithosphere-astenosphere boundary (LAB),

discontinuities ”410” and ”660”.

in transition from East European Craton (EEC) to Variscan Europe (Wilde-Piorko et al., 2005)
