RE: Eagle meteorite

A single mass weighing about 24 lbs was recovered from a ploughed field. The stone was cut in 1984 and a total of 9.46 kg is now preserved. The stone may have fallen in October, 1946 when a bright meteor was seen in the area

The Eagle enstatite chondrite (presently 9.2 kg) was an observed fall in October 1946. It was not recovered until the spring of 1947 and was allowed to remain out-of-doors until 1984. The meteorite appears relatively unweathered, although the absence of oldhamite and the depletion of calcium indicates it has suffered chemical weathering during its 37 years of exposure. Its bulk composition classifies it as an EL6. Its lack of chondrules or remnants of chondrules place it among the most recrystallized of enstatite chondrites. It contains unusual rounded black inclusions, up to 1 cm, composed of the same minerals as the host, but of significantly finer grain size. We conclude Eagle is a post-metamorphic breccia, the breccia inclusions having been rounded by abrasion during regolith processing.
The fall of the Eagle meteorite was observed in autumn, 1946, probably between 1 and 15 October, by Orval and Duane Ketelhut on their farm near Eagle, Cass county, Nebraska.
