# NASA data for LAR 06871 Weathering: B Fracturing: A/B Pairing: LAR 06868 Fa: 29 mol % Fs: 26 mol %
The fusion crust on the exteriors of these meteorites is brown/black with polygonal fractures. The interiors are gray to black matrix, fine grained with some evaporites. Inclusions/chondrules are light colored.
The sections consist of large (up to 2 mm) chondrules in a matrix of finer-grained silicates, sulfides and magnetite. The meteorites are extensively shock blackened. Silicates are homogeneous. Olivine is Fa₂₉₋₃₁ and orthopyroxene is Fs₂₅₋₂₆ across the pairing group. The meteorites are CK5 chondrites
