Caption: Figure 4.
Lunar XRF line-intensity ratio maps from CLASS data. Mg/Al and Al/Si best represent the distinction between the major lunar terranes. High Mg/Si values are not restricted to mare, while FeL/Si is higher in mare but not so evidently in the SPAT. Black lines are mare boundaries from LROC data. As mentioned in Section 2.2, Mg/Al and Al/Si maps were created using 96 s data bins, while the Mg/Si and FeL/Si maps used 296 s binning.
