Bowens reaction series tells us that mafic minerals such as olivine and pyroxene crystallize from a magma chamber at relatively higher temperatures than felsic minerals such as K-feldspar and quartz. If a magma chamber undergoes fractional crystallization during cooling, the remaining magma should be_________ than the parent magma. - correct answerMore felsic The Earth's upper mantle is mainly made of peridotite, an ultramafic igneous rock with lots of olivine crystals. Which type of magma c...
