Immiscible iron- and silica-rich liquids were reported in melt inclusions of lunar basalt and in groundmass glasses of terrestrial volcanics. In fully crystallized plutonic rocks, however, silicate liquid immiscibility has yet to be proven.
WebMost basalt magmas contain abundant molten iron. As magma starts to harden into rock, iron-rich minerals solidify first. Their crystals are pulled into alignment by the Earth’s … WebIron, magnesium, and silicon behave in different ways when magmas are formed by partial melting in a planetary interior and during fractional crystallization of magmas holding chambers beneath volcanoes. This is shown clearly in the graph below, which plots FeO/MgO versus SiO 2. Two distinct trends are shown.
