摘要：

The dextral shear zones in the Hida belt, central Japan, show close temporal and spatial relationships with some of the Late Triassic to Early Jurassic Funatsu granitic intrusions. The Sr isotopic compositions of intrusions associated with the shear zones suggest large crustal contributions to the magma chemistries. In contrast, granitic intrusions not accompanied by shear zones show less crustal signatures. It is suggested that contrasting characteristics in the two types of intrusions reflect different stress conditions. -from Author
