a, Regional geological map of the northeast SPA and the Apollo basin, modified from Ivanov et al.20. b, FeO content distribution of the candidate sampling region derived from Multiband Imager (MI) data48. c, TiO2 content distribution of the candidate sampling region derived from LRO WAC data49. d, The relative albedo distribution of the candidate sampling regions based on CE-2 DOM data. e, Geological units and CSFD dating results for the candidate sampling regions in this study, Ap4 (yellow dashed line) and Ap5 (blue dashed line) are CSFD areas defined by ref. 21. Solid lines represent the three candidate regions (F, L and B). The coloured regions (F_A, L_A and B_A) are the areal extent for CSFD dating in this study.
