The ore which contains both iron and copper is chalcopyrite. Its molecular formula is CuFeS2. Its molecular formula shows that it contains both iron as well as copper.
Iron and magnesium are the two common minerals in basalt. The rock is poor in silica though.
Calcium and Iron
Some asteroids are. Most are composed of a mixture of silicate minerals. Others are a mixture of the two.
Many minerals have these properties. Calcium for example is contained in both Limestone and in Dolomite. Indeed, calcium carbonate occurs in two forms - as Aragonite, and as Calcite. Iron is contained in both Hematite and in Iron Pyrites.
