The progressive nucleation of minerals from the melt leaves the magma depleted in certain elements. this change in magma composition is called magmatic differentiationand accounts for the great variety of igneous rocks found in nature. the separation of liquid and solid phases through crystal settling further contributes to this diversity.
use your understanding of bowen’s reaction series and crystal settling to determine which of the following mineral associations should not be found in nature.
olivine, potassium feldspar, quartz
