Zircon U-Pb geochronology and geochemistry of granites in …
Previous studies show that U-rich granites are the main uranium source for the granite-hosted uranium deposits in South China (e.g., Bonnetti et al., 2018; Hu et al., 2008; Min et al., 1999; Zhang and Zhang, 1991).

Origin of the Low δ18O Signals in Zircons from the Early
The origin of low δ 18 O signals in zircons from the Early Cretaceous A-type granites in eastern China has long been disputed. It is uncertain whether the 18 O-depleted features were inherited from high-temperature hydrothermal altered source rock or resulted from water-rock interaction after emplacement. In this paper, zircon oxygen isotopes in the ∼130 …

Low-δ18O A-type granites in SW China: Evidence for the …
Here we provide evidence for plume-slab interaction mainly based on in situ zircon Hf-O isotope analyses, as well as whole-rock elemental and Sr-Nd-Hf isotope analyses, on the Late Permian and Early Triassic A-type granites on the margin of the Emeishan LIP in SW China. These granites show typical A-type geochemical characters, such as high ...

We investigated Late Permian to Triassic granites from South China to investigate these issues. Ore-related granites with high REE contents (192–467 ppm) intruded in the Late Permian have high K 2 O and Zr + Ce + Nb + Y contents, high Ga/Al and K/Na ratios and low CaO contents, and are classified as aluminous A-type granite derived from ...
