Define Thermal metamorphism Thermal metamorphism … Webgeology. metamorphism, mineralogical and structural adjustments of solid rocks to physical and chemical conditions differing from those under which the rocks originally formed. Changes produced by surface conditions such as compaction are usually excluded. The most important agents of metamorphism include temperature, pressure, and fluids.
WebApr 12, 2024 · Epizone is the uppermost zone that is nearest to the earth’s surface and is characterized by mechanical and chemical metamorphism, that constitutes hydrous silicates. Shearing stress is strong and hydrostatic pressure is low in this zone. The temperature is relatively low or moderate (<300 degrees Celsius) and Cataclastic … WebFigure 6.4. 1: Garnet schist. Geologists use index minerals that form at certain temperatures and pressures to identify metamorphic grade. These index minerals also provide important clues to a rock’s sedimentary protolith and the metamorphic conditions that created it.
