Experts are baffled by structures under Pacific that shouldn't exist
According to current scientific theories, the anomalous material in the lower mantle, about 600 miles (1,000km) beneath the water, 'should not be found' there. Described as a 'major mystery', the ...
Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
In the uppermost lower mantle, seismic anisotropy is ubiquitous near subducting slabs, where shear waves with horizontal ...
