Discreditation of Platarsite : A S-Rich Variety of Sperrylite

Andrew M. Mcdonald, Louis J. Cabri
Published: 29 September 2023
The Canadian Journal of Mineralogy and Petrology (2023) 61 (5): 1039–1044.
DOI: https://doi.org/10.3749/2300021
...Andrew M. Mcdonald; Louis J. Cabri Abstract Platarsite is a relatively uncommon platinum-group mineral, reported from several world-wide localities, that has been defined as both Pt(As,S) 2 and PtAsS in the literature. It was first described using material from the Onverwacht mine, eastern Bushveld...
