This work contains new data about sub-effusive magmatic breccias with quartz-potassium feldspar-porphyry cement of rhyolite-trachyriolite composition. These breccias are associated with biotite-hornblende granites (rapakivi), probably, form the feeding channel of an effusive center confined to the Salmi Batholith.
