Fig. 4: Colored cooling paths representing modeled maximum cooling time compared to linear cooling of 3.9 °C My⁻¹ (dotted line).

Neither solution conflicts with the formation of FAS 60025 (green line). FAS liquidus from Rapp and Draper⁷⁰ and cooling path from McCallum and O’Brien⁶⁵. After Borg et al.²².
