Question

Quizplus · Accepted Answer

Intermediate and felsic magmas typically form in subduction zone settings where mafic magma from the mantle interacts with the continental crust, which is more felsic in composition. This interaction can lead to the generation of intermediate and felsic magmas. Additionally, the location of volcanoes on continental margins inland of subduction zones is a common geological setting where these types of magmas are produced, due to the melting of the overriding plate and the mixing of magmas.
