7 Different Types Of Magma

Of all the magma types, basaltic magma is the most flu Though, it is not as fluid as water Once basaltic magma cools down, it becomes basalt rock Basaltic magma is also known as mafic lava Andesitic Magma Andesitic magma has a silica content of 55 to 65 with average levels of sodium, potassium, iron, calcium, and magnesium...
