摘要：

The composition of the regional lower crust (LC) corresponds to K-andesite and fundamentally differs from model LC compositions. The major-element features of the LC are correlated with the types of tectonic structures. Geochemical relations between the LC and mantle are revealed, along with the thickening of the LC due to underplating with alkaline mafic melts.
