| Zusammenfassung |
| We analyze S-receiver functions to investigate variations of lithospheric
thickness below the entire region of Turkey and surrounding areas. The
teleseismic data used here have been compiled combining all permanent seismic
stations which are open to public access. We obtained almost 12 000
S-receiver function traces characterizing the seismic discontinuities between
the Moho and the discontinuity at 410 km depth. Common-conversion-point
stacks yield well-constrained images of the Moho and of the
lithosphere–asthenosphere boundary (LAB). Results from previous studies
suggesting shallow LAB depths between 80 and 100 km are confirmed in the
entire region outside the subduction zones. We did not observe changes in LAB
depths across the North and East Anatolian faults. To the east of Cyprus, we
see indications of the Arabian LAB. The African plate is observed down to
about 150 km depth subducting to the north and east between the Aegean and
Cyprus with a tear at Cyprus. We also observed the discontinuity at 410 km
depth and a negative discontinuity above the 410, which might indicate a zone
of partial melt above this discontinuity. |
