Abstract
A new mineral, stanfieldite, Ca4(Mg,Fe)5(PO4)6, has been found in the Estherville mesosiderite and several pallasites: Santa Rosalia, Albin, Finmarken, Imilac, Mount Vernon, and Newport. The atom ratio Mg:Fe of this mineral varies from 1.5 in Estherville to a constant ratio of about 15 in the pallasites. X-ray, optical, and chemical data for the mineral resemble those for the only intermediate compound in the system Mg3(PO4)2-Ca3(PO4)2.Keywords
