What Is Magma?
1. Basaltic
Also referred to as mafic, basaltic is a type of magma that is high in magnesium and iron, and low in sodium, potassium, and silica. It is the most abundant type of magma and what we often see when volcanoes in Hawaii erupt. It reaches the surface at a temperature of between 1100C to 1250C. When it cools on Earths surface, it forms basalt. Basalt is a dark fine-grained igneous rock that is crushed and popularly utilized as aggregate in construction works. It is often added when constructing concrete structures and laying a road base and pavement. It is also used for floor tiles and stone sculptures.
