Timing of accretion of the Malkhan-Konda Terrane (Western Transbaikal Region) to the Siberian Paleocontinent: Results of U-Pb geochronological studies of the granitoids of the Malkhan Complex

A study attempted to justify the Carboniferous age of the accretion of the Malkhan Konda terrane to the Siberian continent on the basis of geological and UPb geochronological studies of the granitoids of the Malkhan Complex. The geochronological data obtained (336 3 Ma) indicate that the granitoids of the Malkhan Complex of the MalkhanKonda zone are Early Carboniferous in age rather than Early Paleozoic or Riphean as sug gested previously.
