Mafic lava is viscous compared to felsic lava. 2. Mafic lava dominates mid-ocean ridges, while felsic lava is found mostly at convergent areas. 3. Mafic lava flows more easily than felsic lava, and the former has a lower risk of exploding. Since felsics tend to cap steam and other gases, explosive eruptions are more likely. WebMagma compositions are reported in terms of the fraction of mass of oxides (e.g., Al 2 O 3 rather than just Al; Figure 7.10). On average, mafic[1] magma (Figure 7.10, left) is approximately half SiO 2 by mass, and more than 25% iron, magnesium, and calcium oxides by mass.
