Dans Economic geology (Vol. 105 N° 8, Décembre 2010)

The Bushveld Complex contains large ore deposits of platinum-group elements (PGE), V, and Cr. Understanding how these deposits formed is in part dependent on estimates of the compositions of the magmas that filled the Bushveld chamber. Over the [...]

The timing and formation of platinum-group minerals from the creighton Ni-Cu-platinum-group element sulfide deposit, sudbury, Canada : early crystallization of PGE-rich sulfarsenides

Sarah A. S. Dare, Auteur ; Sarah-Jane Barnes, Auteur ; Hazel M. Prichard, Auteur |

Dans Economic geology (Vol. 105 N° 6, Septembre/Octobre 2010)

Platinum-group elements (PGE) are typically hosted in base metal sulfides and by platinum-group minerals (PGM) in Ni-Cu-PGE sulfide deposits. At Sudbury, it appears that the majority of PGE are hosted in PGM. In order to understand why this is t[...]
