Volcanism I: Sources and Composition of Magma
Felsic: Rich in silica (> 65%), poor in iron and magnesium.(E.g. granite, right.) Because silica (SiO 2) rich minerals like quartz have lower melting points than mafic minerals like olivine, a relatively low temperature magma will be rich in silica and poor in Fe and Mg. Conversely, a felsic magma can remain liquid at lower temperatures. Note: On Earth, oceanic crust is always mafic ...
