Magnetic analysis of an Antarctic mesosiderite, ALH-77219
Magnetic analyses are made on an Antarctic mesosiderite ALH-77219,and chemical analyses of metallic grains in the mesosiderite are carried out with the aid of an EPMA. The EPMA analyses show that the metallic phases in ALH-77219 are composed of kamacite of 5-6wt% Ni and taenite of about 50wt% Ni. Th...
