WebbGreenschist. Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically 300–450 °C (570–840 °F) and 2–10 kilobars (29,000–145,000 psi). [1] Greenschists commonly have an abundance of green minerals such as chlorite, serpentine, and … Webb24 feb. 2024 · Nederlands: Schist is een laag- tot middel-metamorf nl:gesteente (doorgaans gevormd bij drukken van 0,1 tot 0,8 GPa en temperaturen van 200 tot 600 graden Celsius).
