Metamorphic Lecture Part 1
Veronica McCann・2 minutes read
Metamorphic rocks form through changes in temperature and pressure, leading to the creation of new minerals and different metamorphic grades based on the intensity of these changes. Different minerals in rocks like andalusite, kyanite, and sillimanite can indicate the temperature and pressure conditions of rock formation, aiding geologists in understanding the metamorphic processes.
Insights
- Metamorphic rocks are created by changes in temperature and pressure, resulting in the formation of new minerals and the reorganization of atoms, with higher grades indicating more significant transformations.
- The presence of specific minerals like andalusite, kyanite, and sillimanite in rocks can reveal the temperature and pressure conditions of their formation, aiding geologists in determining the grade of metamorphism in a region and understanding the rock's history.
