Abstract
The addition of P to a basalt causes a change in the environment of Fe. At low P contents iron is located in the glass structure and the Fe3+/Fe2+ ratio is about 80/20. Further addition of P causes a collapse of the glass structure related to a phase separation that triggers the crystallization of a more reduced iron-containing phosphate phase with a crystalline structure similar to that of stanfieldite, and Mössbauer parameters similar to those of the alluaudite group, together with the format...
