why is pyrite different from that of hematite and magnetite

Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after Economic magnetite deposits primarily occur in layered igneous rocks that formed from the slow cooling of magma, heavy mineral sedimentary deposits, and Early Proterozoic (25 to 16 billion years ago) marine precipitat.
