Extended Data Fig. 10: Fe+Co-Ni-S ternary diagram shown in Fig. 1 with overlayed isothermal ternaries.

From: Mineralogical evidence for hydrothermal alteration of Bennu samples

Extended Data Fig. 10

(a) 25 °C overlay. (b) 100–135 °C overlay. The overlays were extracted from Berger et al., 2016 and based on Vaughan and Craig, 1997 and Naldrett, 1989. Close inspection shows that the data from Bennu sulfides fit closer to the tie line connecting pyrrhotite (4C) with pentlandite for the 25 °C ternary than that for the 100–135 °C ternary.
