Iron w. silicate inclusions, fine octahedrite (IAB-sLH; Off)
Found 1892, 26.3 kg; weathered
An iron meteorite (Ni ~17%) was said to have fallen in 1892 and sold entire in 1951 to the U.S. National Museum. The meteorite was too weathered to have been an observed fall, but has still had some very special features from the meteoritical/mineralogical perspective. Kamacite and taenite are, of course, available in abundance. Schreibersite and lesser amounts of troilite are the most prominent of the minor constituents. However, most surprising was the discovery of phosphate-rich inclusions, which included two new phosphate minerals — brianite and panethite. These new minerals are two of several phosphates discovered in iron meteorites during the past few decades.
Dayton is a member of the large newly consolidated 'IAB complex' consisting of 274 iron meteorites. Dayton itself is part of the IAB-sLH (low Au, High Ni) subgroup of only 10 members as of late 2014.
As of 2000, the main mass (24 kg) remains with the National Museum in Washington. However, numerous moderate pieces have been provided to the Field Museum in Chicago, the Arizona State collection in Tempe, and the Australian Museum in Sydney.
