APPLICATIONS OF THE RE-OS ISOTOPIC SYSTEM IN THE STUDY OF MINERAL DEPOSITS: GEOCHRONOLOGY AND SOURCE OF METALS

, 2005
In mineral deposits the application of the Re-Os system has evolved on two fronts; as a geochronometer in molybdenite, and as a tracer of the source of metals by direct determination of the source of Os contained in the ore minerals.

First in situ Re-Os dating of molybdenite by LA-ICP-MS/MS

, 2019
Conventional dating of molybdenite (Re-187-Os-187) provides one of few options for direct dating of sulfide mineralization. Unfortunately, in situ dating of molybdenite is considered unreliable due to intra-granular decoupling of Re-187-Os-187.

Late Permian–Early Triassic environmental changes recorded by multi-isotope (Re-Os-N-Hg) data and trace metal distribution from the Hovea-3 section, Western Australia

, 2020
The temporal coincidence between the Late Permian mass extinction (LPME) and the emplacement of Siberian Trap basalts suggests a causal link between the two events.

In situ beta decay dating by LA-ICP-MS/MS: applications

The development of in situ laser ablation tandem mass spectrometry (LA-ICP-MS/MS) has made a new range of isotopic systems readily accessible to geologists for dating minerals: Rb–Sr, Lu–Hf, K–Ca, and Re–Os.

Application of Re-Os Geochronolgy to Offshore California Basins

, 2020
The rhenium-osmium (Re-Os) isotope system has historically been used with geochronological applications in the dating of igneous and metamorphic rocks, and in constraining the Earth’s geochemical evolution.
