The origin of platinum group minerals in oceanic crust
Geology, 2023 Abstract Highly siderophile elements (HSEs), including Re and Os, are used extensively as geochemical tracers and geochronometers to investigate the formation and evolution of Earth’s crust and mantle. Mantle rocks are commonly serpentinized, but the effect of serpentinization on the distribution of HSEs is controversial because HSEs are

Behavior of Platinum-Group Elements during Hydrous Metamorphism: Constraints from Awaruite (Ni3Fe) Mineralization [PDF]
Lithosphere, 2023 Natural Fe-Ni alloys are common in meteorites and, presumably, the Earth’s core, where they host significant platinum-group elements (PGE). However, little is known on PGE concentrations in hydrothermal or metamorphic Fe-Ni alloys (i.e., awaruite Ni3Fe ...

Structural and dynamical properties of sperrylite (PtAs2): a molecular dynamics study [PDF]
MATEC Web of Conferences, 2023 There is a demand for platinum group minerals (PGMs) due to the increase in various applications such as electronics, industrial and medical. Sperrylite (PtAs2) is one of the major PGMs, however its recovery by flotation has been reported to be poor. The

Platinum group element mineralization at Musongati (Burundi) : concentration and Pd-Rh distribution in pentlandite [PDF]
, 2017 The mafic-ultramafic intrusions of the Karagwe-Ankole belt in Burundi are considered as a new potential source for platinum group elements (PGE). The intrusions have mainly been studied for their PGE potential with regard to PGE concentration, but the ...
