Figure 4. Scatter plots of diameters, heights, and volumes of the 532 RMDSs measured from NAC-derived DTMs: (a) diameter vs. height; (b) diameter vs. volume

Figure 7. M³-spectra-derived TiO₂ contents of RMDSs and global maria (latitude range +/- 75 degrees). (a) Mean TiO₂ wt% vs. diameter for 2407 RMDSs in seven large mare regions indicated in Figure 2; (b) The TiO₂ content histogram of the measured 2407 RMDSs (green color), compared with the global TiO₂ distribution of all lunar mare regions (red color). Both histograms are normalized to 1, such that the sum of all red or green histogram bins is 1, respectively. The global Ti abundance was taken from the complete lunar mare surface at a latitude range +/- 75 degrees
