U-Pb Geochronology and Trace Element Compositions of Zircon in Biotite Granite from the Bagaladong Pb-Zn Deposit,Tibet and Their Geological Significance
The Bagaladong Pb-Zn deposit is located in the eastern segment of the Gangdese back-arc uplift belt and lacks enough study with no available ages for ores and rocks. Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry( LA-ICP-MS) zircon U-Pb dating and in situ trace elements were carried out for mineralization-related biotite granite in the Bagaladong Pb-Zn deposit and are reported in this paper. The crystallization temperatures of zircons in the biotite granite are obtained by using the zircon Ti t...
