# NASA data for MET 00411 Weathering: B Fracturing: A Pairing: MET 00400
MET 00400, the largest of the masses at 4583.8 g, has an upper regmaglypt-covered surface with a shiny brown coating. A prominent peak is formed by the intersection of several regmaglypts. The lower surface appears to be an earlier generation of fusion crust, with much shallower and larger depressions and a brown, matte finish. The other masses, ranging from 3.2 to 205.1 grams, are irregularly shaped with a shiny brown fusion crust similar to the upper surface of MET 00400. Smaller regmaglypts and depressions are common. Rare knobby surfaces are likely weathered fusion crust. Macroscopic similarities strongly support the pairing of these 23 meteorites. Slices were removed from MET 00400 (4583.8 g), 00401 (205.1g), 00402 (82.6 g), 00403 (58.5 g) and 00412 (8.7g) for examination. These masses were chosen to sample the ranges of masses and locations within the distribution. MET 00400 and 00412 are separated by 5.3 km.
