Crystal textural evolution during a 30 °C temperature cycle. Crystals grown at 870 °C (white diamonds, 22-CSB-03, n_plag = 125) are heated to 900 °C and held for 1 week (green diamonds, 23-CSB-03, n_plag = 465) before cooled back down and held at 870 °C for another week (yellow diamonds, 23-CB-05, n_plag = 219). (a) Crystal length ± 95% confidence interval. (b) 3D short/intermediate axis ratio ± 1 SD. (c) Surface roughness ± 95% confidence interval. Note that while crystal length and surface roughness approach the characteristics of starting plagioclase crystals, 3D crystal aspect ratios do not revert to the original values.
