Magma generation at mor
WebMagmas are formed by partial melting of silicate rocks either in Earths mantle or the continental crust, which in turn forms part of the continental crust and the entire oceanic crust. Types of magma generation Subduction of oceanic crust eventually leads to rising magma bodies. WebThe composition of magma depends on the rock it was formed from (by melting), and the conditions of that melting. Magmas derived from the mantle have higher levels of iron, magnesium, and calcium, but they are …
