The mineralization is associated with a porphyry quartz-monzodiorite to quartz-diorite stock, which intruded into Eocene volcanic rocks consisting of andesite, basalt, and andesitic to dacitic tuff.

A full publication list for Re-Os is available here.
For sulfide minerals, Re-Os geochronology has direct application to the timing and duration of hydrothermal ore deposit formation.
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 Xiaoliugou is a large-scale W (Mo) deposit newly explored in the Northern Qilian Mountains Caledonian fold belt, Northwestern China.
It is a vein and skarn type deposit genetically associated with the Xiaoliugou Caledonian granodiorite stock.
Re-Os isotopic dating for the molybdenite in the deposit yields an isochron age of 462 ± 13 Ma (2σ) and model ages of 436 to 496 Ma.The ages of molybdenite and pyrite are consistent within the analytical errors.Combined with field observations, the data indicate that Mo–Re mineralization in the Baishan deposit is produced by a magmatic-hydrothermal event in an intracontinental extensional setting after late Paleozoic orogeny.The deposit has a grade of 0.06% Mo and a high content of rhenium of 1.4 g/t.Rhenium and osmium isotopes in sulfide minerals from the Baishan deposit are used to determine the age of mineralization.Mineralization occurs as quartz-sulfide veinlets and stockworks, as well as disseminations in the porphyry body and volcanic host rocks, in association with potassic and phyllic alteration.
