By using the stability field of amphibole in the melting experiments, we attempt to estimate the emplacement depth of amphibole-bearing syenites from the Sør Rondane Mountains. The melting relationships of four syenites and one granite were determined in the temperature range of 650-900℃ under water pressure of 0.1-0.3GPa and oxygen fugacities of the FMQ buffer. In two syenites and a granite, the maximum pressure stability limit of amphiboles in subliquidus is lower pressure than 0.35GPa. The emplacement depth of the syenites from the S∅r Rondane Mountains is similar to that of syenites from the Yamato Mountains.
