Question

1. the diagram of bowens reaction series below indicates the relative temperatures at which specific minerals crystallize as magma cools. (temperatures at which minerals crystallize) temperature of cooling magma 1400°c 800°c olivine pyroxene amphibole biotite mica orthoclase muscovite mica quartz sodium - rich plagioclase feldspar calcium - rich plagioclase feldspar which statement is best supported by bowens reaction series? a) most minerals crystallize at the same temperature. b) most felsic minerals usually crystallize before most mafic minerals. c) muscovite mica and quartz are the last minerals to crystallize as magma cools. d) biotite mica is the first mineral to crystallize as magma cools.

Explanation:

Bowen's Reaction Series shows the sequence of mineral crystallization as magma cools. Mafic minerals (like olivine) crystallize at high - temperatures, while felsic minerals (like quartz) crystallize at lower temperatures. Muscovite mica and quartz are among the last minerals to crystallize as magma cools.

Answer:

B. Most felsic minerals usually crystallize before most mafic minerals.
