Iron meteorite, octahedrite (IIIAB, Om)
Found 1889, 163 kg.

A mass of 163 kg was found in 1889 by G .W. Cornelius on his farm, located about 13 km south of Independence. The mass was about 1 m below the surface and interlocked in the roots of an ash tree. An additional piece discovered in 1892 in nearby Grant County was identified as a companion piece several decades later. Buchwald (1975) provided a detailed look at the Fe-Ni metal assemblage of kamacite, taenite, and plessite [7.45% Ni; .48% Co] as well as the associated sulfides, phosphides, and nitrides. Indeed, the carlsbergite (CrN) was one of the first instances of a nitride recovered in any iron meteorite. The pentlandite and limonite are products of terrestrial weathering and alterations.

Kenton County is the most massive of the 25 recovered Kentucky meteorites and is one of the 6 IIIAB irons recovered there.
