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 is concluded that Eagle is a postmetamorphic breccia, the breccia inclusions having been rounded by abrasion during regolith processing.
