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.

本研究揭示了越南东北部 PiaOac花岗岩的锆石U-Pb年代、Hf同位素组成以及全岩成分。这些数据表明，PiaOac花岗岩形成于晚白垩纪至同造山期后环境。花岗岩及其相关矿化的形成时代与我国西南地区相似。它们共同构成了东西向延伸的晚白垩纪岩浆作用和成矿带。其起源与纽特提斯板块向北俯冲有关。
