Figure 8. Results of geochemical thermometry for the LZa rocks at
P =1 kbar and 0.1 wt.% H2O
in the starting compositions. Thin lines correspond to the equilibrium crystallization trajectories
calculated at closed O2 conditions for six
Ol -
Pl gabbros. The temperature of 1145
5oC is
assumed to indicate that intrinsic to the residual liquid (Table 3). Thick line represents
calculations for the average LZa composition at
QFM (see Figure 5). Two dashed lines belong to
the samples LA-347 and LA-753 are excluded from further considerations.
