The composition of the mafic magma was 50% anorthite, 30% diopside, and 20% forsterite. The liquid composition of the magma will change along a path from M to Xb as the … Magma consists of liquid rock that usually contains suspended solid crystals. As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near the surface consists of materials in solid, liquid, and gas phases. Most magma is rich in silica. Rare nonsilicate magma can form by local melting of nonsilicate mineral deposits or by separation of a magma into separate immiscible silicate and nonsilicate liq… small windows above doors
