Research subject. Amphiboles from the Kaalamo metamorphosed multiphase clinopyroxenite-gabbronorite-diorite complex in the Northern Ladoga region. Aim. To elucidate the genesis of all amphibole rock types in the complex. Methods. Amphibole morphology was analyzed using optical (Olimpus BX53) and electron microscopy (JEOL JSM-6510LA). The chemical composition of minerals was analyzed using a JEOL JED-2200 energy-dispersive spec trometer. Mineral parageneses were modeled by Gibbs energy minimization using the MAGEMin software. Results. In the rocks of the Kaalamo complex, amphiboles of igneous and metamorphic origin were identified. The presence of magmatic amphiboles (magnesiohastingsites and magnesioferrigornblendites) in phase 1 pyroxenites and phase 2 gabbrodiorites was revealed. These amphiboles are characterized by elevated titanium contents and crystallization temperatures higher than the regional metamorphic temperature. Some of the amphiboles in the pyroxenites gabbro, and gabbrodiorites, as well as all the amphiboles in phase 3 diorites and tonalites, are metamorphic and could have formed either through the replacement of pyroxenes or from earlier magmatic amphibole. Discrimination diagrams with projections of the petrochemical parameters of amphiboles (content of titanium, magnesium number et al.) are suitable for a preliminary assessment of their nature; however, they should not be relied upon solely due to the overlapping compositions of minerals of different origins. Conclusions. The metamorphosed rocks of the Kaalamo complex contain not only metamorphic but also igneous amphiboles, indicating the saturation of the parental magma with water.
