Re-Os isotopic dating procedures for organic-rich samples
Shiyou shiyan dizhi, 2021 The rhenium-osmium (Re-Os) geochronometer is newly developed technology and has been regarded as a promising radiometric tool for the direct dating of the deposition of source rock, hydrocarbon generation, migration and consequent alteration (e.g., thermal cracking, thermochemical sulphate reduction), and oil-source correlation.

Geochemistry of Kauai shield-stage lavas: Implications for the chemical evolution of the Hawaiian plume [PDF]
, 2003 We measured He, Sr, Nd, Pb, and Os isotope ratios and major and trace element concentrations in stratigraphically and paleomagnetically controlled shield-stage lavas from Kauai, Hawaii. The range of 3He/4He ratios (17–28 RA) from Kauai is similar to that

Ore Geology Reviews, 2020 Abstract The Fule deposit is one of the carbonate-hosted Pb-Zn deposits in southeastern part of the Sichuan-Yunnan-Guizhou (SYG) metallogenic province, SW China. This deposit is hosted by dolomitic limestone and dolomite of the Yangxin Formation with Zn-Pb ore reserves of more than 20 million tons (Mt).
