Abstract The magnetochemical synthesis, as presented, derives from an integration of the magnetic property systematics developed with corresponding bulk chemistry and petrology, and the results of mixing and reduction responses which feature in the production of the lunar regolith. Magnetochemical properties of the lunar soils are correlated with the Al/Si ratio and telescope spectral reflectivity curves. Magnetochemical diagrams utilizingχ p(paramagnetic susceptibility ≃ FeO) andI S(saturation magnetization ≃ Fe metal) serve to classify lunar samples, indicate the extent of mixing, and demonstrate that although reduction does take place in production of the regolith, the role of mixing is quite significant. The relative metal size distribution and magnetic stability for various rock types and soils of varying Al/Si values are reflected in theR I(ratio of saturation isothermal remanence-I R, to saturation magnetization -I S) vsR H(ratio of remanent coercive force -H R, to coercive force -H C) plot. All magnetic hysteresis loop parameters considered vary systematically according to the Al/Si values. All Apollo landing sites have distinct telescope curves correlated with petrology, chemistry, Al/Si values, and magnetic properties. Magnetic properties of sites not visited can now be reasonably estimated based on telescope reflectivity curves and orbital geochemical experiments.
