Note that standard deviations are not given for those categories where
the number of analyses (N) is \<3. N = number of analyses, Std. Dev. =
standard deviation, MBAS = mare basalts, S&RB = soils and regolith
breccias, BX = polymict breccias, AMET = Antarctic lunar meteorites.
Highland monomict rocks (HMCT in Fig. 8.2) are listed by individual rock
type name (anorthosite, norite, and troctolite; see section 6.3).
