    Problem: What is the big difference between basaltic and granitic/pyroclastic magma?

    Solution:
    Basalt and granite are both igneous rocks, but differ in composition: basalt is mafic (iron-rich) while granite is felsic (enriched with lighter elements such as silicon, oxygen, aluminium, sodium, and potassium). The represent the two extremes of igneous rocks. Magma can also be intermediate in composition (half-way between mafic and felsic). The composition of the magma depends on the source material. Melted continental crust is rich ...
