WebbMarble that has been exposed to low levels of metamorphism will have very small calcite crystals. The crystals usually grow in size and as the level of metamorphism progresses. Clay minerals within the marble will … WebbIn igneous rock, this is used to determine the rate at which the material cooled: large crystals typically indicate intrusive igneous rock, while small crystals indicate that the rock was extrusive. Metamorphism of rock composed of mostly a single mineral, such as quartzite or marble , may increase grain size ( grain growth ), while metamorphism of …
WebbMetamorphic rocks can exhibit great variation in crystal size; in general, the size of crystals increase as the grade of metamorphism increases. During the recrystallization process, certain metamorphic minerals, including garnet, staurolite, and andalusite, tend to develop a few large crystals [28,29]. WebbDuring the process of metamorphism and igneous rock formation, physical and chemical shifts can take place, both of which contribute to the formation of crystals within the rock. In order to form a crystal lattice structure, the atoms of the minerals are forced to move and rearrange themselves as a result of the heat and pressure.
