Iron Pyrox

img

Iron is an element, represented by the symbol Fe. There is not technically a "chemical formula" for iron because it is an element.

The crust is presumed to be com- posed primarily of rocks containing feldspar, calcium aluminum silicate, and lesser pyroxene,iron and magnesium silicate; the crust also contains basalt in the mares, which con- tains less iron and more titanium than earth basalt. The mantle is thought to be made up of calcic peridotite, containing both pyroxene and feldspar.
