Characterization of thermal and stress perturbations during emplacement of granitic plutons in NW Iran

The plutonic units in the northwest of Sanandaj-Sirjan Zone emplaced under different thermal and stress regimes. Primary biotite was changed by hydrothermal fluids into illite, muscovite, and sericite, and phyllic and argillic alteration spread across the plutonic units. The intrusion margins exhibi...
