We have considered the following characteristics of the crust and upper mantle of the Pacific Belt: seismic wave velocit>
anomalies, mechanical stress and shear deformation rate fields, heat flow and the pattern of metallogenic provinces of the
Belt. It has been noted that there exist certain regularities in distribution of the above mentioned geophysical characteristics
and metallogenic zones within the Belt, displayed by prevalence of the lithophile elements in the Asia-Australian part of the
Belt, and of the chalcophile ones within the American part.
