Liquefaction of unprocessed mineral ores - Iron ore nes and nickel oreBy Dr Martin Jonas, Brookes Bell, Liverpool. (see Figure 1). This suddenly reduces the friction between particles, and thus the Rock Environments. Metamorphic Environments. What Is Metamorphism?. Metamorphism. . Changes rock via temperatures and/or pressures unlike those in which it initially formed. All metamorphic rocks have a . – Write down . 5 things . you learned in the first . 3 . weeks of class!.

Formed from intense heat and pressure!. Sources of Heat. 300-1400 degree Celsius temperatures are needed for Metamorphism.. Sources of heat include:. Magma or lava. Metamorphism. Metamorphic rocks: appear to have changed in their structure or chemical composition since their creation or formation.. Originally sedimentary or igneous. Altered by heat, pressure, or exposure to hot fluids in earth’s crust. By Cara . Chae. -Banks. And. Ian . Gevanthor. Distiguishing. Characteristics. Color: Yellowish gray (often mistaken for gold).
