COMPLEX LITHOSPHERIC STRUCTURE UNDER THE CENTRAL BALTIC SHIELD FROM SURFACE WAVE TOMOGRAPHY

Bruneton M.; Pedersen H.A.; Farra V.; Arndt N.T.; Vacher P.; Achauer U.; Alinaghi A.; Bock G.; Wilegalla K.; Ansorge J.; Kissling E.; Sandoval S.; Friederich W.; Wielandt E.; Grad M.; Guterch A.; Heikkinen P.; Hyvönen L.T.; Ikonen J.-P.; Korja A.et al. (2004)

Regional seismic tomography provides valuable information on the structure of shields, thereby gaining insight to the formation and stabilization of old continents. Fennoscandia (known as the Baltic Shield for its exposed ...
HIGH-ORDER PERTURBATIONS OF THE PHASE VELOCITY AND POLARIZATION OF QP AND QS WAVES IN ANISOTROPIC MEDIA

Farra V. (2001)

An approximate expression of the eikonal equation and the polarization vector may be obtained in weakly anisotropic media from first-order perturbation theory. The advantage of this approximation for qP wave is that the ...
LAYERED LITHOSPHERIC MANTLE IN THE CENTRAL BALTIC SHIELD FROM SURFACE WAVES AND XENOLITH ANALYSIS

Bruneton M.; Pedersen H.A.; Vacher P.; Kukkonen I.T.; Arndt N.T.; Funke S.; Friederich W.; Farra V. (2004)

Information on the structure of the upper mantle comes from two main sources. Regional seismic studies provide indirect information on large portions of the lithosphere, and mantle xenoliths provide direct information about ...
NON-LINEAR SURFACE WAVE PHASE VELOCITY INVERSION BASED ON RAY THEORY

Bruneton M.; Pedersen H.A.; Farra V. (2002)

The development of temporary and permanent broad-band seismic arrays reinforces the need for advanced interpretation techniques in surface-wave analysis. We present a new method based on 2-D paraxial ray theory of inverting ...
