Hallo Forum,
Hier mal der "Originalton" Hutchison ohne Übersetzung, damit sich nicht eventuell irgendwelche Fehler einschleichen:
Metamorphism = response of a mineral assemblage to change in its environment:
- prograde,
thermal response of a mineral assemblage to
heat; may involve dehydration.
- retrograde, aqueous response of a mineral assemblage to the introduction or redistribution of water.
- shock response of a mineral assemblage to transient increases in pressure and
temperature caused by impact.
