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.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Re-Os Isotope Characteristics of the Huize Ultra-large Lead-Zinc Deposit, Northeastern Yunnan Province: Constraints on the Himalayan Metallogenic Dynamic Background

Yankuang ceshi, 2018
BACKGROUND The Huize ultra-large lead-zinc deposit is a typical MVT or HZT type deposit in the lead-zinc polymetallic belt. This deposit is known as a unique metallogenic system and germanium enrichment. Due to the low mineralization temperature and lack

Re-Os isotope system of sulfide from the Fule carbonate-hosted Pb-Zn deposit, SW China: Implications for Re-Os dating of Pb-Zn mineralization

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).
