Basaltic magma (Physical Geology) Fiveable
Basaltic magma is a type of magma that is low in silica content and rich in iron and magnesium, which gives it a darker color and higher density compared to other types of magma It is primarily produced in oceanic settings, often from partial melting of the mantle, leading to its primary association with volcanic activity at midocean ridges and hotspotsHigh silica content in the andesitic lava contributes to causing this high viscosity and low silica content in the basaltic lava means it is of a lower viscosity Both lavas are formed at different plate boundaries which is why they have different silica contents: What are the differences between basaltic and andesitic lava?
