Re os age dating
Rhenium-Osmium dating is carried out by the isochron dating method.Isochrons are created by analysing several samples believed to have formed at the same time from a common source.Ore minerals investigated in detail include molybdenite, pyrite and arsenopyrite which have been applied to understand the origin of porphyry, Sed Ex, VMS, IOCG and Orogenic Au deposits globally.Some key papers include: Using Re-Os isotopes to determine the deposition age of petroleum source-rock formation (organic-rich shales) is a major research theme, both in terms of technical development and application.
For example, the boundaries of many Phanerozoic systems, epochs, and stages are marked by the deposition of black shale units, several of which are coincident with mass extinction events.
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.
Development of Re-Os geochronology for crustal matrices has been ongoing since 1998 in the laboratory.
This work has resulted in major advancements in the direct isotopic dating of crustal sulfide minerals, petroleum source-rocks, and natural hydrocarbons, using Re-Os isotopes.
