A classification of sets of major oxide chemical data on lunar rocks and lunar glasses using the G-mode central method is presented. These data were selected from the Lunar Data Base using as criteria (1) the measurement of the amount of oxides such as SiO2, Al2O3, TiO2, and Na2O by the same investigators and (2) a sum of these major oxides of between 97.0 and 103.0 wt.%. The G-mode central method attempts to recognize homogeneous sets or groups of samples, with the original multivariate distribution reduced to a set of G values which follow a 'quasi-Gaussian univariate' distribution. Fifteen groups of lunar rocks were recognized with all eight variables contributing to the recognition of 12 retained groups; eight families and 16 groups of lunar glasses were recognized and vector means for the oxide wt.% total are given.
