The comparison of the experimental results with evolution trends calculated by the thermodynamic models MELTS and Comagmat shows that neither model predicts the experimental phase relations with sufficient accuracy. Ilmenite and Magnetite of a Tholeiitic Basalt. A natural parental Klauea tholeiitic composition (see Supplementary Table B for chemical composition) was used as starting material for our crystallization experiments, partly because Hawaiian basalts have played a central role in our understanding of the formation and evolution of mafic magmas ( Garcia, 2015 ). Tholeiitic basalts that are interleaved with felsic rocks of the Duffer Formation but that do not form part of either recognized geochemical basalt-dacite series (i.e., Duffer F2 and F3; see below) are high-Ti tholeiites (Table 20.3) identical in trace element concentration and normalized patterns to the high-Ti tholeiites of the underlying Mount Ada Basalt (Smithies et al., 2005a).

This type of basalt is present on Earth in much greater amounts than alkali olivine basalt, which occurs along continental rifts and on oceanic islands.
