Re-Os isotopes natural hydrocarbons are directly related to source-rock Re-Os isotope character and in some cases Re-Os geochronology of hydrocarbons is possible.

The Asian continent hosts some of the world’s major Phanerozoic gold deposits and gold provinces, which were formed under a variety of tectonic settings and by various geological processes ( Goldfarb et al., 2014; Zaw et al., 2007, 2014; Khomich et al., 2014 , and references therein).

Furthermore, the result also implies that the age of the Gaixian Formation in the Maoling district is older than 2316±40 Ma.

The Ag-rich sulfide ore (tetrahedrite & galena) is mainly hosted by steeply-dipping siderite-quartz veins intersecting folded quartzite and siltstone from the Ravalli Group of the Mesoproterozoic Belt Supergroup.

The age of mineralization in the district has been controversial since the first geological studies.
