We analyzed the Se isotopic composition of black shales and related kerogen and sulfide fractions from the Zunyi Ni–Mo–Se deposit, the La’erma Se–Au deposit and the Yutangba Se deposit in southern China to constrain metal sources and accumulation processes, both subjects of disagreement in the scien...
