New data about the quartz porphyry dikes of the Salmi batholith, belonging to the anorthosite-rapakivigranite complexes of rocks is presented. The relative relationships of various igneous rocks of the Salmi batholith and metasomatites; the isotopic age of quartz porphyry by U-Pb method using LA-ICP-MS; the temperature of zircon formation by Ti content are determined. Sulfide melt inclusions in zircons were also found.
