LA-(MC)-ICP-MS zircon U-Pb dating of porphyry from Baoshan copper deposit of Dayaoshan uplift area in Guangxi

The Baoshan copper deposit is located at the uplift in southern Dayaoshan uplift area,Guangxi. The mineralization is closely related to the Late Yanshanian quartz porphyry. Using LA-( MC)-ICP-MS zircon U- Pb dating,zircons from the granite porphyry has a weighted mean age of 94. 8 ± 0. 6 Ma( MSWD = 0. 17),zircons from the Cu-mineralization quartz porphyry has a weighted mean age of 93. 9 ± 0. 4 Ma( MSWD = 2. 5). These data suggest that the...
