The root of the Urals: evidence from wide-angle reflection seismics

The existence of a crustal root beneath the Urals which would deflect the position of the Moho by some 20 km is still largely controversial. A French-Russian project carried out a wide-angle-reflection seismic experiment across the Middle Urals to image the Moho topography along a 175-km profile running approximately east-west north of Ekaterinburg. New data show a 6-km Moho deflection beneath the central part of the orogen. The Moho...
