WebBowen’s reaction series (Figure 7.6) has two pathways for minerals to form as magma cools: on the left is the discontinuous series. This refers to the fact that one mineral is … WebAs the magma cools and crystallizes, the composition of the solid will change along a path that goes from point Xb to point M. Because anorthite crystallizes first, its phenocrysts will form at their respective points, and the composition of the liquid will change to favor diopside and forsterite.

WebIf magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving the intrusive igneous rock a coarse-grained or phaneritic texture. The individual crystals in phaneritic texture are readily visible to the unaided eye. WebJan 11, 2024 · Extrusive igneous rocks form above the surface.

WebAs minerals with lower melting points turn into liquid magma, those with higher melting points remain as solid crystals. This is known as partial melting. As magma slowly rises … The minerals that make up igneous rocks crystallize at a range of different temperatures. This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid.
