... whitmoreïte apparaît comme le résultat d’un processus d’auto-oxydation de la ferrostrunzite. Ce processus suggère qu’un minéral proche de la phosphoferrite se serait formé lors de la première étape, se transformant ensuite en kryzhanovskite par auto-oxydation. Abstract Phosphate masses have been found...
