Washington, May 1 : Scientists have developed a new digital model of Europe's crust, which would help in understanding the many millions of years of development of the European Continent.

The model was developed by M. Tesauro und M. Kaban from GeoForschungsZentrum Potsdam (GFZ) and S. Cloetingh from the Vrije Universiteit in Amsterdam.

For many years, intensive investigation of the Earth's crust has been underway. However, different research groups in Europe have mostly been concentrating on individual regions. Hence, a high-resolution and consistent overall picture has not been available to date.

With the present study, this gap can now be filled.

By incorporating the latest seismological results, a digital model of the European crust has been created. This new detailed picture allows for the minimization of interfering effects of the crust when taking a glance at the deeper Earth's interior.

The model of Europe's crust shows an astonishing diversity.

For example, the crust under Finland is as deep as one only expects for crust under a mountain range such as the Alps. It is also amazing that the crust under Iceland and the Faroer-Islands is considerably deeper than a typical oceanic crust.

A detailed model of the Earth's crust, i.e. from the upper layers to approx. a depth of 60 km, is essential to understand the many millions of years of development of the European Continent.

This knowledge supports the discovery of the commercial importance of ore deposits or crude oil in the continental shelf or in general with the use of the subterranean, e.g. for the sequestration of CO2.

It also contributes to the identification of geological hazards such as earthquakes.
