Recent progress on the research of Re–Os geochronology and Re–Os elemental and isotopic systematics in petroleum systems

open access: yesJournal of Natural Gas Geoscience, 2020
Re–Os geochronometer has been used in the dating of generation-accumulation, thermal cracking, and thermochemical sulfate reduction of crude oil and the oil-source correlation of petroleum systems in recent years.

Comparison of isotope data obtained with Sm-Nd and Re-Os methods for minerals and rocks from the Ozernoe ore occurrence, Salla-Kuolajarvi belt

open access: yesVestnik MGTU, 2021
Sm-Nd isochrone, drawn for rock-forming and sulfide minerals from the Ozernoe ore occurrence, indicates albitite age of 1,759 ± 11 Ma. It shows synchronous formation of albitite and sulfide mineralization, and fully corresponds to the earlier defined age

Re-Os dating of the Raobazhai ultramafic massif in North Dabie

open access: yesChinese 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.

Protogenetic sulfide inclusions in diamonds date the diamond formation event using Re-Os isotopes [PDF]

open access: yesGeology, 2021
Sulfides are the most abundant inclusions in diamonds and a key tool for dating diamond formation via Re-Os isotopic analyses. The manner in which fluids invade the continental lithospheric mantle and the time scale at which they equilibrate with preexisting (protogenetic) sulfides are poorly understood yet essential factors to understanding diamond ...

Heterogeneous Os isotope compositions in the Kalatongke sulfide deposit, NW China: the role of crustal contamination [PDF]

open access: yes, 2012
Re-Os isotope compositions of mantle-derived magmas are highly sensitive to crustal contamination because the crust and mantle have very different Os isotope compositions.

Geochronology and geochemistry of the Shanagen hydrothermal vein-type Mo deposit in Derbugan metallogenic belt of the NE China and their geological significance

open access: yesFrontiers in Earth Science, 2023
The Shanagen hydrothermal vein-type Mo deposit belongs to the Derbugan metallogenic belt, which is located in the Ergun block, NE China. The Mo mineralization is mainly developed in sericitized quartz siltstone around alkali-feldspar granite.

Re-Os (ICP-MS) DATING OF MARINE OIL SHALE IN THE QIANGTANG BASIN, NORTHERN TIBET, CHINA; pp. 47-55 [PDF]

open access: yesOil 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 measure­ment.

The possible existence of Hs in nature from a geochemical point of view [PDF]

open access: yes, 2006
A hypothesis of the existence of a long-lived isotope 271Hs in natural molybdenites and osmirides is considered from a geochemical point of view. It is shown that the presence of Hs in these minerals can be explained only by making an additional ad hoc ...
