The stratigraphic heights are those of Gibb and Henderson (1996). The number of angles measured is given by n. The median clinopyroxene–plagioclase–plagioclase dihedral angle is given by Θ_cpp, with the uncertainties calculated according to Stickels and Hücke (1964). The standard deviation is given by SD
