What Has A Higher Melting Temperature Magnesium Rich Pyroxene Or Iron Rich Pyroxene?

What Has A Higher Melting Temperature Magnesium Rich Pyroxene Or Iron Rich Pyroxene? The iron-rich pyroxene crystals have a higher melting temperature, because it heats at a higher temperature than magnesium-rich pyroxene crystals, therefore it would have to have a higher melting temperature. Do all minerals have the same melting point? Every mineral has a
