Fig. 3: Model ages of the crater candidates ages and their host units.
From: The Tharsis mantle source of depleted shergottites revealed by 90 million impact craters
Vertical and horizontal grey bands correspond respectively to the range of CRE ages and the crystallization ages3,4 of depleted shergottites launched 1.1 Myr ago including NWA 7635 (2.40 ± 0.14 Gyr). Error bars are generated based on crater counts. Oblique colour lines illustrate the expected displacement in time if different cratering rates are considered (range of a factor of 2 around the reference impact flux21). The red circle outlines the two craters whose model age of their host unit is compatible with the range of crystallization age of depleted shergottites launched 1.1 Myr ago: Tooting and 09-000015. Note that two ages are reported for Tooting, one (308 ± 41 Myr) corresponding to immediate surrounding (thin outline), and the other (\({1.77}_{-0.58}^{+0.69}\)Gyr) accounting for large craters around Tooting and partially filled-up by more recent lavas (thick outline). Craters in the legend are sorted by size (Supplementary Table 2).
