Re-Os Isotopic Dating of Arsenopyrite from Auriferous Quartz Vein-type Gold Deposits in the Southwestern Margin of Jiangnan Orogen

open access: yesYankuang ceshi, 2016
Quartz vein-type gold deposits of Southeastern Guizhou Province in the southwestern margin of Jiangnan Orogen, which are typical orogenic gold deposits, are hosted in Neoproterozoic Banxi Group sub-greenschist facies metamorphic rocks.

Dating of hydrocarbons with Re-Os isotopes: Experimental investigation of the behavior of Re-Os in petroleum [PDF]

open access: yes, 2013
Le géochronomètre Re-Os a fait ses preuves dans son application aux huiles et bitumes pétroliers. Cependant, l’application de ce système sur les fluides pétroliers souffre d’un manque de compréhension de la géochimie pétrolière de Re et Os, des mécanismes de remise à zéro du géochronomètre et par conséquent des évènements réellement datés.

Re-Os geochronology for sulfides and organic-rich sediments. [PDF]

open access: yesNatl Sci Rev
Rhenium and osmium are both siderophilic and chalcophilic, exhibiting a strong affinity for organic-rich materials. This makes the Re-Os chronometer a valuable complement to geochronometers based on lithophile elements.

Origin of the Xulaojiugou Pb–Zn Deposit, Heilongjiang Province, NE China: Constraints from Molybdenite Re–Os Isotopic Dating, Trace Elements, and Isotopic Compositions of Sulfides [PDF]

open access: yesMinerals
The Xulaojiugou Pb–Zn deposit, situated in the eastern Xing’an-Mongolia Orogenic Belt (XMOB), represents a medium-scale Pb–Zn deposit in central Heilongjiang Province, NE China. The mineralization occurs mainly near the contact zone of porphyritic biotite granite, medium-grained monzogranite, and marble in the Early Cambrian Qianshan Formation ...

Morozkinskoye gold deposit (southern Yakutia): age and ore sources

open access: yesЗаписки Горного института, 2021
The paper presents the results of the comprehensive isotope geochemical (Re-Os, Pb and δ34S) study of sulfide mineralization of the Morozkinskoye deposit. The ore zones of the deposit are localized in the syenite massif of Mount Rudnaya, which is located

Re‐Os isotope systematics in carbonates from Serpent Mound, Ohio: Implications for Re‐Os dating of crustal rocks and the osmium isotopic composition of Ordovician seawater [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2004
Eleven core samples of Ordovician carbonates and shale from within and nearby the Serpent Mound (Ohio) cryptoexplosion structure were analyzed for Re‐Os isotopes. Whole‐rock samples span a large range in measured 187Os/188Os (0.714 to 6.083), and exhibit a linear correlation of 187Os/188Os with 187Re/188Os.

The Jurassic Gangmei Mo-W deposit in Guangdong Province and its implication for Mo-W mineralization in South China

open access: yesSolid Earth Sciences, 2022
South China developed large-scale Mesozoic magmatism and polymetallic mineralization, especially Jurassic W-Sn and Mo-W mineralization. Compared with W-Sn deposits, Mo-W deposits in South China have received less attention.
