Rocks don’t just change randomly under heat and pressure.
They change in predictable ways.
In this video, we explore metamorphic facies, not as a list to memorize, but as a simple idea:
minerals form only within specific ranges of pressure and temperature.
Why do certain minerals always appear together?
How can a rock reveal the depth and conditions it once experienced?
And why are facies better than vague terms like “low-grade” or “high-grade”?
This is a slow, intuitive look at how rocks act as natural thermometers and barometers.
🌍 What this video explores
• What metamorphic facies really mean
• Why minerals form in stable combinations
• Pressure-temperature conditions recorded in rocks
• Greenschist, amphibolite, granulite facies explained simply
• Special facies like blueschist and eclogite
