Tetrahedral components of augite and hypersthene in Atlantis Bank gabbros calculated from Lindsley and Andersen (1983) and contoured for equilibrium temperatures for coexisting pyroxene pairs. The thin black lines are joins connecting coexisting mineral compositions. Temperature contours are in degrees centigrade, whereas dashed lines show inferred extensions of these contours. En, enstatite; Fs, ferrosilite; Di, diopside; Hd, hedenbergite
