Fig. 5: Potential mare basalt in south polar region.

a Comparisons on FeO abundance and Mg#. In the main image, gray dots represent samples from maria units50 around the globe, blue dots represent samples from south polar region (>65°S), and red dots represent the overlap between the two. The upper part of X-axis shows FeO abundance histogram, and the right part of Y-axis shows Mg# histogram. b Potential distribution of mare basalt in south polar region. The base image is the WAC global mosaic map (WAC_GLOBAL_P900S0000_100M). The yellow markers represent sampling points in areas of exposed mare basalt. All of the above results were obtained using equal-area sampling (Methods).
