Dataset of PiaOac granites and deposits
This study presents zircon U-Pb ages and Hf isotope compositions and whole rock compositions of the PiaOac granites in NE Vietnam. These data indicate that the PiaOac granites were formed in Late Cretaceous and syn- to post-orogenic setting. The formation times of the granite and related mineralization are similar to those in SW South China. They consitute together a E-W trending Late Cretaceous magmatism and metallogeny belt. Their origin is related to the northward subduction of the Neo-Tethys Plate.
