Geochrology, Geochemistry and Petrogenesis of Ore-Related Granite in the Dongping Tungsten Deposit in Wuning County, Jiangxi~Province

The Dongping tungsten deposit，located in the eastern section of Jiangnan orogenic belt in Jiangxi Province, which is a newly discovered giant “five-story” quartz vein type wolframite ore deposit. In order to study the metallogenic magmatic rock of the age, source and tectonic background of the Dongping tungsten deposit, this paper has carried out detailed zircon U-Pb chronology, major-trace element geochemistry，and Sr-Nd isotope studies of the Dongping metallogenic biotite granite. LA-ICP-MS zircon U-Pb dating results demonstrate the age of Dongping biotite granite is 132.9~1.4 Ma...
