Santa Cruz CA (SPX) May 18, 2006 - Halfway to the center of the Earth, at the
boundary between the core and the mantle, lies a massive folded slab of rock
that once formed the ocean floor and sank beneath North America some 50 million
years ago. A team of seismologists led by scientists at the University of
California, Santa Cruz, detected the slab by analyzing seismic waves reflected
from the deepest layer of the mantle beneath an area off the west coast of
Central America.
