Discriminating ore fertile and barren granites using zircon Ce and Eu anomalies – Perspective from late Mesozoic (Yanshanian) granites in South China

Redox conditions are widely considered to be important to magma fertility, and have been estimated using different proxies, notably the biotite Fe3+/Fe2+ ratios and zircon Ce and Eu anomalies. In this research, we compiled a large number of zircon REE data from both the fertile (Cu–(Au)–Mo, Cu–Pb–Zn, W–Sn, W and Sn) and barren Yanshanian (Jurassic-Cretaceous) granites from South China to test whether zircon REE compositional differences can...
