MARGIN: auto 0cm" class=MsoNormal>man’,’serif’" lang=EN-US>In this paper, the authors get the isochronal age between 30 Ma and 29 Ma for deposit using the Rb-Sr dating of sphalerite and Sm-Nd dating of mineralization stage calcite. By discussing the age of mineralization, it can be concluded that there are twice mineralization events in mining area, one for the main copper mineralization occurred between Late Paleocene and Early Eocene, according with the short-term stress relaxation stage after strong compression of Indian plate and Eurasia plate; another was main lead and zinc polymetallic mineralization between 30 Ma and 29 Ma, corresponding to the Late Eocene-Early Oligocene stress relaxation stage after compression.mas-microsoft-com:office:office" />
