Zircon SHRIMP dating of granite from The cathodoluminescence (CL) textures indicate that some of the cassiterite crystals from the wolframite-cassiterite quartz vein system have growth zonations, i.e. Dating on cassiterite (zone II) yields a wehted average 206Pb/238U age of 159.5 ± 1.5 Ma (2σ, MSWD = 0.4), i.e. Zircon SHRIMP dating from Qaidamshan granite shows that the granite age is 446 Ma, similar to that of eclogite in the UHP belt. We think that both granite and.
Zircon - pedia Zircon from the three granite units has a wehted average 206Pb/238U age of 159.8 ± 0.3 Ma (2σ, MSWD = 0.3). Zircon is a mineral belonging to the of nesosilicates. Its chemical name is zirconium. Zircon is a common accessory to trace mineral constituent of most granite. has played an important role during the evolution of radiometric dating.
