Question

Quizplus · Accepted Answer

Mafic magmas are distinguished by low viscosity, which means they are more fluid and less sticky than magmas of higher silica content. Mafic magmas typically contain less than 50% silica and have a high content of magnesium and iron. This composition gives them a darker coloration, hence the name "mafic" (short for magnesium and ferric).
