The way to overcome the difficulty in Re-Os dating of molybdenite.

Proceedings of the Japan Academy, Series B, 1990
When a molybdenite was dissolved and treated by the conventional chemical procedure, it was difficult to achieve the isotopic equilibrium between the 187Os radiogenically accumulated in the molybdenite and“common”Os added as a kind of internal standard, even after chemically complete decomposition. It is evident that this isotopic disequilibrium effect

Re-Os isotope system in organic-rich samples for dating and tracing: Methodology, principle, and application

, 2023
In the last three decades, significant progress has been made in the investigation of rhenium-osmium (Re-Os) isotopic system in organic-rich samples. The Re-Os geochronometer can provide precise absolute depositional ages of organic-rich sediments (ORS ...
