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. WebbA pegmatite is an igneous rock showing a very coarse texture, with large interlocking crystals usually greater in size than 1 cm (0.4 in) and sometimes greater than 1 meter (3 ft).Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite.However, rarer intermediate composition and mafic pegmatites … small group listWebbthe slow cooling at depth allows large crystals to grow A porphyritic texture where large … song that\u0027s all by genesis

Bowen (1887–1956), Bowen's reaction series allows geologists to predict chemical composition and texture based upon the temperature of a cooling magma. Bowen's reaction series is usually diagramed as a "Y" with horizontal lines drawn across the "Y."
