H/E_r and plasticity indices (W_p/W_T) for each individual nanoindentation performed in this work (filled squares, Nakhla and ALHA77005 shergottite), for olivines (left) and pyroxenes (right). For comparison purposes, terrestrial olivine and NWA 12008 values (olivines and pyroxenes) are also shown as 2σ ellipses from a bivariate normal fit, which were measured under the same experimental conditions as those in this work (P. Grèbol-Tomàs et al. 2025). Terrestrial pyroxene data was not feasible to obtain. Histograms on the top and right axes of each plot show the respective marginal distributions for all datasets obtained under the same experimental conditions. Literature values for other lunaites and a diogenite (E. Peña-Asensio et al. 2024), Chelyabinsk (C. E. Moyano-Cambero et al. 2017) and returned Chang’e-5 (J. Nie et al. 2023; S. Qiao et al. 2026, personal communication) and Itokawa (S. Tanbakouei et al. 2019), measured under different experimental parameters as our setup, are also shown. Data points are shown with the same marker and color scheme as in Figure 6.
