WebAug 4, 2024 · We argue that the phase transition from quartz to coesite in the felsic rocks may explain the microstructural differences between the studied mafic–ultramafic and felsic rock samples. The presence of coesite, which has a higher strength than quartz, may result in an increase in the bulk strength of felsic rocks, leading to strain localization ...

WebMay 6, 2024 · The sequence in which minerals crystallize from a magma is known as the Bowen reaction series (Figure 3.3. 1 and Figure 3.3. 3 ). Of the common silicate minerals, olivine normally crystallizes first, at between 1200° and 1300°C. As the temperature drops, and assuming that some silica remains in the magma, the olivine crystals will react ...
