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.

WebbAs long as there is silica remaining and the rate of cooling is slow, this process continues down the discontinuous branch: olivine reacts to form pyroxene, and the pyroxene reacts to form amphibole. Under the right conditions amphibole will form to biotite. Webb21 dec. 2024 · At the slowest cooling rates (10, 20, 50 °C/h), the ferrite appears to be almost entirely consumed by intermetallic formation. The scale of the intermetallic structure makes it difficult to tell if there is any ferrite remaining between the …
WebbVery rapid cooling can lead to production of a glass with no crystal nuclei. Slow cooling will tend to allow the nucleation and growth of equilibrium phases. Crystal nucleation will not necessarily occur immediately when a magma is cooled rapidly in one step from above the liquidus to a temperature at which nucleation is possible. Webb1 jan. 2010 · It was also found that slow cooling favours P enrichment in C2S [13]. …
WebbThe slow cooling process allows crystals to grow large, giving the intrusive igneous rock a coarse-grained or phaneritic texture.
