Magma series
WebThere are three principal ways rock behavior crosses to the right of the green solidus line to create molten magma: 1) decompression melting caused by lowering the pressure, 2) flux melting caused by adding volatiles (see more below), and 3) heat-induced melting caused by increasing the temperature. WebSeries (1), (2) and (3) magmas were drawn from an isotopically depleted mantle which was enriched in incompatible elements shortly before or synchronous with melting. These magmas were produced by variable degrees of melting of garnet or spinel lherzolite.

WebTypes of magma are determined by chemical composition of the magma. Three general types are recognized: Basaltic magma -- SiO 2 45-55 wt%, high in Fe, Mg, Ca, low in K, … WebThat magma, now intermediate in composition, continues to rise and assimilate crustal material; in the upper part of the crust, it accumulates into plutons. From time to time, the magma from the plutons rises toward surface, leading to volcanic eruptions. Mt. Garibaldi (Figures 4.1 and 4.2) is an example of subduction-related volcanism.
