Why do high temperature and pressure conditions lead to the formation of foliated and non-foliated metamorphic rocks?
Answer (2)
Answer:Here's why high temperature and pressure conditions lead to the formation of foliated and non-foliated metamorphic rocks: 1. Metamorphism: The Process of ChangeHeat: Heat provides the energy for the chemical reactions that transform existing minerals into new ones. This process is called recrystallization.Pressure: Pressure squeezes the minerals together, causing them to align in a particular direction. This alignment is key to the development of foliation. 2. Foliated Metamorphic RocksFormation: Foliated rocks form when pressure is applied unevenly, causing minerals to align in parallel layers. This creates a layered or banded appearance.Examples: Schist, gneiss, slate, and phyllite. 3. Non-Foliated Metamorphic RocksFormation: Non-foliated rocks form when pressure is applied evenly, or when the minerals are not easily deformed.Examples: Marble (formed from limestone), quartzite (formed from sandstone), and hornfels. Here's a breakdown of the key factors:Pressure: Uneven pressure leads to foliation, while even pressure or resistant minerals lead to non-foliated rocks.Mineral Composition: Some minerals are more easily deformed than others. For example, mica minerals readily align under pressure, contributing to foliation.Temperature: Higher temperatures allow for more significant recrystallization and mineral changes, which can influence the development of foliation. In summary:High temperature and uneven pressure create the conditions for foliated metamorphic rocks.High temperature and even pressure, or resistant minerals lead to non-foliated metamorphic rocks.
