Fig. 3: Temperature variation and zonation of actinolite grains.

a–e Grain-scale temperature maps of representative actinolite samples from drill core LD1687. f Histogram showing number of pixels extracted from temperature maps vs. actinolite temperatures. g Solubility curve of CuCl:HCl as a function of temperature for a HCl-bearing fluid saturated with respect to chalcopyrite; fO2 conditions correspond to the pyrite-pyrrhotite-magnetite buffer46. Temperature maps axis is scaled in micrometers.
