Images of the study area taken by SELENE. a TC images. Yellow spots indicate the locations of lobate scarps. b Embossed image of grayscale image of the digital terrain model (DTM) made by Haruyama et al. (2008) from SELENE data. Highland with the altitudes above \(-1000\) m is out of range to highlight low-relief topographic features in the mare. Orange and blue lines indicate grabens and sinuous rilles, respectively. Yellow boxes indicate the areas where CSFD measurements were taken. c Spectral ratio images shown in false color (749/414 nm on red, 749/950 nm on green, 414/749 nm on blue) with the mare units defined in this study. d Topography overlaid with the embossed image shown in b. Crater ages of the units in Ga are indicated as well
