Writeup from MB 108:

Edmore        43°22’24.81"N, 84°58’30.37"W

Michigan, United States

Find, doubtful fall: 1939

Classification: Iron meteorite (IIIAB)

History: "Seen to fall" and recovered on a farm in Michigan, supposedly in 1939. It was used as a doorstop to the barn on the farm. Original finder/owner told the current owner the story of recovery when he bought the farm. When the current owner sold the farm he took the meteorite with him and then to Central Michigan University, who submitted a piece to the SI for classification.

Physical characteristics: Light-brown fusion crust covers part of the meteorite. Modest to moderate weathering.

Petrography: This meteorite is a medium octahedrite, with kamacite lamellae of ~0.8 mm. Taenite between kamacite exhibits pronounced zoning. Schreibersite grains up to 4 mm show extensive fracturing. No fusion crust is evident on the section examined. Weathering is modest in the section.

Geochemistry: (J.T. Wasson, UCLA): INAA data, Ni = 89.1, Co = 5.41 (both mg/g), Cr=17, Cu=120, Pt=4.5, Ga=20.9, As=14.1, W=0.34, Ir=0.70, Au=1.621 (all µg/g), Re <50 ng/g.

Classification: Iron, IIIAB.
