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...

If a magma chamber undergoes fractional crystallization during cooling, how will the remaining magma differ from the parent magma? - correct answer It will be more felsic What type of magma can be produced when upper-mantle peridotite undergoes decompression along mid-ocean ridges? - correct answer basaltic Mineral - correct answer -Naturally ocurring -inorganic element or compound -has an orderly internl structure and characteristic chemical composition, crystal form, and physical prope...
