Resumo
The Transbaikal sector of the Mongol–Okhotsk orogenic belt displays a well-consistent geochemical and metallogenic zoning. The axial zone of the belt, which is controlled by the Mongol–Okhotsk suture zone from the north, is composed of reduced ilmenite-series rocks. Tin, tungsten, and rare-metal deposits and occurrences previously distinguished by S.S. Smirnov as a rare-metal belt are confined to the ilmenite-series rocks. The reduced rocks are framed from the north and south by oxidized magnetite-series rocks with chalcophile mineralization. The distribution zones of the ilmenite-series rocks correspond to anomalies with lower gravity and magnetic fields, whereas the magnetite-series oxidized rocks correspond to anomalies with higher gravity and magnetic fields.
