Age and source constraints for the giant Muruntau gold deposit, Uzbekistan, from coupled Re-Os-He isotopes in arsenopyrite
Ryan M. Morelli,Robert A. Creaser,Reimar Seltmann,Finlay M. Stuart,David Selby,Torsten Graupner +5 more
TL;DR: The authors used Re-Os geochronology to precisely determine the age of main-stage gold mineralization at Muruntau to be 287.5 ± 1.7 Ma, which overlaps the emplacement of proximal post-tectonic granitoid magmatism.

Re-Os sulfide geochronology of the Red Dog sediment-hosted Zn-Pb-Ag deposit, Brooks Range, Alaska
TL;DR: In this paper, a 10-point isochron on both massive and vein pyrite yields an age of 338.3 ± 5.8 Ma and is interpreted to represent the age of main stage ore.

Constraints on the genesis of gold mineralization at the Homestake Gold Deposit, Black Hills, South Dakota from rhenium–osmium sulfide geochronology
TL;DR: The Homestake gold deposit, located in the Black Hills, South Dakota, USA, is one of the largest known hydrothermal gold deposits globally, with total mining production exceeding 40 Moz Au.

Rhenium-Osmium Geochronology of Arsenopyrite in Meguma Group Gold Deposits, Meguma Terrane, Nova Scotia, Canada: Evidence for Multiple Gold-Mineralizing Events
TL;DR: In this paper, an analysis of arsenopyrite from bedding-concordant veins from The Ovens locality, southwest Meguma terrane, yielded a precise Re-Os isochron age of 409 ± 5 Ma.

The Timing of Yellowknife Gold Mineralization: A Temporal Relationship with Crustal Anatexis?
TL;DR: In this paper, the authors show that pyrite associated with orogenic gold mineralization from the Con deposit in the ca. 2700 Ma Yellowknife greenstone belt has an Re-Os isochron age of 2591 ± 37 Ma.
