Mineral composition igneous rocks are comprised of a combination of minerals belonging to the silicate mineral class or group Bowen's mineral series describes an orderly sequence of mineral formation and separation from a cooling magma and explains the specific mineral combination or association in a rock discontinuous series refers to the formation of different minerals as a magma cools continuous series refers to the formation of plagioclase minerals with slightly different compositions at different magma temperatures hydrothermal solutions--after almost all rock forming minerals have formed (separated) from a cooling magma, hot watery (hydrothermal) solutions remain with dissolved concentrations of precious metals which later precipitate valuable ore deposits click here to see Bowen's mineral series Magma composition can change as cooling progresses and minerals separate--- also (as mentioned before) magma assimilation can cause a change in composition gabbro/basalt, diorite/andesite, and granite/rhyolite are the 3 main categories of magma compositions 3.
