Bowen's reaction series - Wikipedia
The minerals at the top of the illustration (given aside) are first to crystallize and so the temperature gradient can be read to be from high to low with the high temperature minerals being on the top and the low temperature ones on the bottom. Since the surface of the Earth is a low temperature environment compared to the...Read More

This research thus includes experi-.Read More
Minerals, Rocks & Rock Forming Processes
Different minerals crystallize at different temperatures (olivine at high temperatures, quartz at low temperatures), and therefore the mineral composition of an igneous rock can tell us something about the cooling history of that rock. The realization that types and modes of occurrences of igneous rocks can be tied to a common...Read More

Types of Metamorphism
Mar 14, 2017 ... High-grade metamorphism takes place at temperatures greater than 320oC and relatively high pressure. As grade of metamorphism increases, hydrous minerals become less hydrous, by losing H2O, and non-hydrous minerals become more common.Read More
Metamorphism & Metamorphic Rocks
Increasing temperature increases the atomic vibrations of the minerals, and because vibrating atoms occupy more volume than still atoms, high temperature minerals tend to be less dense than low temperature minerals. Increasing temperature also increases the speed at which elements can react to form new minerals.Read More
