Abstract: Stirrings beneath California A high-resolution Rayleigh-wave seismic tomography study of the uppermost 200 km of mantle beneath the Gulf of California has provided evidence for localized centres of buoyancy-driven upwelling in the underlying mantle. Low shear velocities, similar to those beneath the East Pacific Rise oceanic spreading centre, were found to underlie the entire length of the Gulf, but there are three concentrated locations of anomalously low velocities spaced about 250 km apart. These seismic velocity anomalies may indicate that partial melting triggers dynamic upwelling driven by either the buoyancy of retained melt or by the reduced density of depleted mantle.
