U-Pb SIMS geochronology of ore-bearing magmatic rocks of the Malmyzh and Poni gold-copper-porphyry ore fields (Lower Amur River Region)

New data obtained by mineralogical, petrographical, geochemical and isotope-geochronological studies of magmatic rocks within the Malmyzh and Poni gold-copper-porphyry ore fields are discussed. Geochronological data show a simultaneous – Cenomanian radiological age of their magmatic crystallization: 97–99 и 93 Ma, respectively. Based on comparative analysis of studied samples from the Malmyzh and Poni ore fields both with one another and with magmatic rocks from worldwide porphyry deposits, it is attempted to better understand geodynamic nature of their formation and detect the world areas with similar conditions of adakitic granitoid magmatism.
