The host structure is the Palabora (Phalaborwa) carbonatite complex, formed in part from a magma dominated by carbonate minerals, such as calcite, rather than the familiar silicates (quartz, feldspars, etc) of typical igneous rocks such as granite and gabbro. The intrusive complex also contains grains of minerals such as baddeleyite and zirconolite, and has been dated at 2060 Ma (million years).

Both phases of carbonatite, and the foskorite, contain abundant magnetite, whereas the pyroxenite is essentially free of magnetite. The foskorite has around 50% magnetite, while the carbonatites together average 27%. Copper occurs in the foskorite and both phases of the carbonatite, but is best developed within the transgressive carbonatite.
