# NASA data for EET 87501 Weathering: B/C Fracturing: A Pairing: EET 87500 Fs: 30-31 mol % NTL: 0.21 ± 0.04 krad
Deep regmaglypts are present on the weathered surface of EET 87500, a mesosiderite. Only a few small patches of fusion crust remain on the surface. Abundant pyroxene inclusions, up to 2.5 cm in their longest dimension, are visible on the exterior. This meteorite is moderately weathered. The interior consists of approximately two-thirds silicates, coarse-grained pyroxene and plagioclase, and one-third metal. The exterior of EET 87501 has regmaglypts and a thin fusion crust with flow marks. The interior is identical to EET 87500 except that it appears to be more weathered.
