High-Precision Re-Os Geochronology of the newly Discovered Lihefu Deposit Reveals the ∼145 Ma Mo Mineralization in Daye District, Eastern China

Abstract

High-precision Re-Os ages for molybdenite from the Lihefu Mo skarn deposit suggest a single pulse of Mo mineralization ranging from 144.36 to 144.56 Ma, spanning only 200 ± 60 ka. These ages indicate that Lihefu and other Cu-Mo-W deposits associated with small felsic intrusions formed at the earliest period in this district. The small intrusions in the same period (~145 Ma) may have great potential for Cu-Mo-W mineralization.
