Rhenium-osmium (Re-Os) data from migrated hydrocarbons establish the timing of petroleum emplacement for the giant oil sand deposits of Alberta, Canada, at 112 ± 5.3 million years ago. This date does not support models that invoke oil generation and migration for these deposits in the Late Cretaceous. Most Re-Os data from a variety of deposits within the giant hydrocarbon system show similar characteristics, supporting the notion of a single source for these hydrocarbons. The Re-Os data… Expand
Rhenium–osmium (Re–Os) geochronology of crude oil from lacustrine source rocks of the Hailar Basin, NE China
Re–Os radiometric dating of crude oil can be used to constrain the timing of hydrocarbon generation, migration or charge. This approach has been successfully applied to marine petroleum systems;Expand
Revisiting Rhenium-Osmium Isotopic Investigations of Petroleum Systems: From Geochemical Behaviours to Geological Interpretations
Recent decades have witnessed an increasing number of studies investigating petroleum systems with the application of rhenium-osmium (Re-Os) isotopic geochemistry. Here, we review the use of theExpand
Rhenium-osmium geochronology and geochemistry of ancient lacustrine sedimentary and petroleum systems
The Re-Os geochronometer is a valuable tool able to provide precise depositional ages of marine organic-rich sedimentary rocks as well as the generation age of hydrocarbons. In addition, Os isotopesExpand
Hydrocarbons/Rhenium–Osmium (Re–Os): Organic-Rich Sedimentary Rocks
The first application of the Re–Os isotope geochronometer to ORR demonstrated that the Re–Os data, although imprecise, could yield the depositional age of sedimentary successions (Ravizza andExpand
Rhenium – Osmium Geochronology : Sulfides , Shales , Oils , and Mantle
Rhenium–osmium geochronology is based on radioactive decay of Re to Os with a half-life of 41.6 b.y. – about 10 times the age of the earth. Both Re and Os are siderophile-chalcophile elements, thatExpand
Rhenium–osmium geochronology and oil–source correlation of the Duvernay petroleum system, Western Canada sedimentary basin: Implications for the application of the rhenium–osmium geochronometer to petroleum systems
The Re–Os geochronometer has been applied to many petroleum systems worldwide. However, it is debated if the Re–Os systematics in petroleum actually record the timing of oil generation. Here, weExpand
Evaluation of the rhenium-osmium geochronometer in the Phosphoria petroleum system, Bighorn Basin of Wyoming and Montana, USA
Rhenium–osmium (Re–Os) geochronometry is applied to crude oils derived from the Permian Phosphoria Formation of the Bighorn Basin in Wyoming and Montana to determine whether the radiogenic ageExpand
187Re-187Os geochronology of Precambrian organic-rich sedimentary rocks
Abstract Global correlations of Precambrian stratigraphic successions can be hampered by the coarse resolution of biostratigraphic and chemostratigraphic records, and by the scarcity of reliable U–PbExpand

Osmium isotopes as petrogenetic and geological tracers
Abstract Using terrestrial osmium-enriched samples of known ages, we have shown that 187 Os/ 186 Os varies with time in result of the 187 Re β − radioactivity. Such a variation in the earth's mantleExpand

Enhanced mantle-to-crust rhenium transfer in undegassed arc magmas
Observations of high rhenium concentrations and low Yb/Re ratios in arc-type melt inclusions indicate strong enrichment of Rhenium in undegassed arc rocks, and consequently the continental crust, which results in a crustal estimate of ∼2 p.p.b.rhenium, as compared to previous estimates. Expand
