Immiscible iron and silicarich melts in basalt
Silie liquid immiscibility in basalt petrogenesis is a contentious issue. Immiscible iron and silicarich liquids were reported in melt inclusions of lunar basalt and in groundmass glasses of terrestrial volcanics. In fully crystallized plutonic rocks, however, silie liquid immiscibility has yet to be proven.
