Elevated d18O in JH zircons provided the first evidence of magmas that had interacted with material from low-temperature, water-rich environments (i.e., likely sedimentary assimilants). Would d18O be a useful way to discriminate JH zircons crystallized from hydrous basalt sources vs. magmas with metapelitic assimilants?
