We have considered the following characteristics of the
crust and upper mantle of the Pacific Belt: seismic wave velocity 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.
