"The Lanjiagou Mo deposit is located in the eastern part of the North China Craton. Rhenium and osmium isotopes in molybdenites from the Lanjiagou porphyry Mo deposit have been used to determine the timing of mineralization," investigators in Beijing, People's Republic of China report.
"Molybdenite was analyzed mainly from granite porphyry, which is characterized by moderate to strong silicification. Rhenium concentrations in molybdenite samples are between 33 and 48 mu g/g. Analysis of eleven molybdenite samples yields an isochron age of 181.6 +/- 6.5 Ma (2 sigma)," wrote C.M. Han and colleagues.
The researchers concluded: "Based on the geological ...
