Extended Data Fig. 1: Plot showing the average D/H for minerals and glasses versus shock pressure for shergottites.

There is no apparent correlation between shergottite type and shock implantation of hydrogen. Where: Y = Yamato 980459, T = Tissint, Z = Zagami, Sh = Shergotty, S = Sayh al Uhaymir 005, D = Dar al Gani 005, Q = Queen Alexandra Range 94201, and L = Los Angeles. D/H data are compiled in Supplementary Table 2. Note that only non-impact glass/groundmass D/H reported from Q and L, and only feldspathic glass reported from S and D. Error bars represent standard deviation of the mean for D/H and the range in reported shock pressures^42,43.
