Research progress and prospects for the Re-Os dating of petroleum systems

Acta Petrologica Sinica, 2022
The rhenium-osmium (Re-Os) radiogenic isotope system has been widely applied on the geochronology of the key timings of the petroleum systems. Here we focus on the application of Re-Os isochron age constructed with crude oil and low-maturity bitumen ...

Re-Os Dating of Molybdenites from Southern India: Implication for Pan-African Metallogeny

Journal Geological Society of India, 1994
Abstract Rhenium-Osmium (Re-Os) dating of two molybdenite samples from the alkali granite and pegmatite of Ambalavayal in northern Kerala (S. India) yielded ages of 567±28 Ma and 566±77 Ma, respectively. These ages closely compare with the previously determined Rb-Sr whole rock age of 595±20 Ma Rb-Sr for granite, and K-Ar biotite age of ...

Re-Os Dating of Pyrrhotite from the Chaoshan Gold Skarn, Eastern Yangtze Craton, Eastern China

International Geology Review, 2008
The Chaoshan gold skarn, located in the central part of the Tongling Cu-Au-Mo district in eastern China, consists of 10 ore bodies occurring along an intrusive contact between the Early Cretaceous Baimangshan pyroxene diorite (BPD) and limestones of the Middle Triassic Nanlinghu Formation.

In situ Re-Os dating of molybdenite by LA-ICP-MS/MS

Molybdenite is the principal host mineral for rare metals such as molybdenum and rhenium and is widely distributed in various hydrothermal deposits. Owing to its high rhenium content and negligible common osmium, molybdenite is an ideal target for Re–Os isotopic dating.

Implications of high-precision Re-Os molybdenite dating of the Navachab orogenic gold deposit, Namibia

Geochemistry: Exploration, Environment, Analysis, 2014
This paper presents and discusses the first Re-Os molybdenite dates from the Navachab orogenic gold deposit, the largest non-Witwatersrand gold resource in southern Africa. At the deposit, a late-kinematic, auriferous, quartz-vein swarm and associated Ca-Mg-Fe-Mn skarn ( sensu lato ) alteration crosscut the ...
