Figure 14. Plot of 5 0(magnetite) vs. 5 0(quartz) for amphibolite facies quartzites from Black Mtn., New Hampshire. The nearly parallel tie-lines indicate that fractionations are self-consistent for these eight samples from one outcrop. The average oxygen isotope temperature of 542°C is in excellent agreement with that from petrology (530°C). (from Rumble (1978).
