Isotope Geochemistry of the Dachang Tin-Polymetallic Ore-Field
The granite in this area has been dated by Rb-Sr at 99 to 115 Ma, and its genesis is discussed.
The isotope compositions of Pb, S, O, C of the minerals at various ore-forming stages of every belt in the orefield have been measured, and their variation regularities are interpreted. The genesis and source matter of the deposits are also discussed.
