# NASA data for ALH 81023 Weathering: B Fracturing: A/B Pairing: ALH 81018 Fa: 25 mol % Fs: 21 mol % ²⁶Al: 36 ± 1 dpm/kg
ALH 81023 was found on the ice in Antarctica as 2 large pieces, 2 small pieces and many tiny chips. None of the pieces fit together, but are obviously related. The matrix is light gray with many dark colored chondrules, irregular shaped inclusions and troilite(?) grains that show relief from the exterior surface. Some fusion crust is present on each piece. Weathering is moderate. A minute amount of white deposit is present on one piece.
