The tholeiitic magma series is one of two main magma series in subalkaline igneous rocks, the other being the calc-alkaline series. A magma series is a chemically distinct range of magma compositions that describes the evolution of a mafic magma into a more evolved, silica rich end member. Rock types of the tholeiitic magma series include tholeiitic basalt, ferro-basalt, tholeiitic basaltic andesite, tholeiitic andesite, dacite and rhyolite. The variety of basalt in the series was ori… WebIron, magnesium, and silicon behave in different ways when magmas are formed by partial melting in a planetary interior and during fractional crystallization of magmas holding chambers beneath volcanoes. This is shown clearly in the graph below, which plots FeO/MgO versus SiO 2. Two distinct trends are shown.
