Fig. 1.
Petrogenetic grid showing metamorphic mineral assemblages stable across Martian pressure–temperature–depth ranges relevant to the work of Wright et al. [modified after (4)]. Zeo—zeolite facies; PrA—prehnite actinolite facies; PP—prehnite pumpellyite facies; PA—pumpellyite actinolite facies; GR—greenschist facies. Mineral assemblages are indicated by ACF diagrams and abbreviations are actinolite (Act), chlorite (Chl), laumontite (Lm), lawsonite (Lws), pumpellyite (Pm), prehnite (Pr), and zoisite (Zo). The red square represents the chemical composition of Martian basalt (9).
