Re-Os dating of the Raobazhai ultramafic massif in North Dabie
Chinese Science Bulletin, 2004 The ultramafic massif at Raobazhai in North Dabie is located in the suture zone between the Yangtze craton and North China craton. The Re-Os isotope compositions of the massif are used to decipher the origin and tectonics of the ultramafic rocks involved in continental subduction and exhumation.

Radiometric dating of marine-influenced coal using Re–Os geochronology [PDF]
Earth and Planetary Science Letters, 2015 Abstract Coal deposits are integral to understanding the structural evolution and thermal history of sedimentary basins and correlating contemporeous estuarine and fluvial delatic strata with marine sections. While marine shales may readily lend themselves to Re–Os dating due to the dominance of hydrogenous Re and Os, the lack of a chronometer for ...

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 (ICP-MS) DATING OF MARINE OIL SHALE IN THE QIANGTANG BASIN, NORTHERN TIBET, CHINA; pp. 47-55 [PDF]
Oil Shale, 2008 Marine oil shale from the Shenglihe oil shale section in the Qiangtang basin, northern Tibet, China, was dated by the Re-Os technique using Carius Tube digestion, Os distillation, Re extraction by acetone and ICP-MS measureÂment.

First in situ Re-Os dating of molybdenite by LA-ICP-MS/MS [PDF]
Mineralium Deposita, 2019 Conventional dating of molybdenite (187Re-187Os) provides one of few options for direct dating of sulfide mineralization. Unfortunately, in situ dating of molybdenite is considered unreliable due to intra-granular decoupling of 187Re-187Os. In this study, we developed a new analytical protocol for studies of micron- to grain scale 187Re-187Os ...
