Seven chips of primarily matrix material from the Antarctic meteorite ALHA81005 were analyzed by ferromagnetic resonance (FMR) and magnetic hysteresis techniques. The FMR spectra of two chips have a resonance at g~2.1 that resembles the g~2.1 resonance that is characteristic of lunar soils. Thus the FMR spectra are consistent with the lunar regolith being a progenitor for the matrix material. For the two chips, Is/FeO~5 units which is equivalent to a value for an immature lunar soil. The total concentration of metallic iron is on the order of 0.11 equivalent wt.% which is within the observed range for Apollo 16 rocks and soils.
