The Kirchenovskoye gold-silver deposit is one of the fairly large deposits in the Olovyanninsky region. In addition to rich ore mineralization, the distribution of noble metals in the host rocks is of interest. For five selected rocks, the contents of noble metals (Rh, Pd, Ag, Pt, Au) were determined, the main part of which is represented by metasomatites: beresitized granite, graphite metasomatite (gneiss), graphite shale, mudstone and rocks from the weathering crust. For this, the method of mass spectrometry with inductively coupled plasma (ICP MS) was used. Promising mineralization for Au, Ag, and Pd (mudstone, graphite shales and gneisses) have been identified. The concentration of noble metals in ores and host rocks occurred due to the removal of these metals from the granitoid massif by hydrothermal solutions.
