“…Outcrop-scale structures show high-temperature deformation in schlieren and chromitemylonites, whereas microstructural studies of the Zunhua chromites (Li et al, 2002;Huang et al, 2004;Polat et al, 2006;Kusky et al, 2007) documented high-temperature grain boundary pullaparts, preferred crystallographic slip on (010) [100] slip systems in olivine inclusions, asymmetric recrystallized tails on orthopyroxene porphyroclasts, high-temperature deformation bands in inclusions in olivine, and used established paleothermometers (Holtzman, 2000;Nicolas, 1989;Nicolas and Azri, 1991), to estimate the crystallization temperatures of the chromite to have been between 1000 °C and 1250°C, consistent with recent high-pressure experimental work (Raterron et a., 2012;Wang et al, 2017;Wallis et al, 2019). Age constraints on the formation of the mélange, the blocks contained therein, and of the chromite grains are described in detail in W.B.…”
