Accumulation of magnetite by flotation on bubbles during decompression of silicate magma

Magnetite (Fe(3)O(4)) is an iron ore mineral that is globally mined especially for steel production. It is denser (5.15 g/cm(3)) than Earth’s crust (~2.7 g/cm(3)) and is expected to accumulate at the bottom of melt-rich magma reservoirs. However, recent studies revealed heterogeneous fluid bubble nu...
