Constraints on Alpine Fault (New Zealand) mylonitization temperatures and the geothermal gradient from Ti-in-quartz thermobarometry
... lonites and protomylonites during Alpine Fault deformation contain similar concentrations of Ti as coarser grains (e.g., Figs. 4, 8). This is atypical behavior, since increasingly finer grains formed during exhumation ...
