21. Hard metamorphic rocks are usually placed by waterfalls or streams. 22. Orthopyroxene is an important constituent of some metamorphic rocks such as granulite. 23. Metamorphic rocks like gneiss and mica dominate the rest of the territory.24. Identifying a protolith is a major aim of metamorphic geology. 25. Protoliths are non-metamorphic rocks and thus have no protoliths themselves. 26. Continental metamorphic and granitic basement rocks have been dredged from both knolls. 27. The Pooranoo Metamorphics were deposited at the end of the Capricorn Orogeny. 28. Lawsonite is a metamorphic mineral typical of the blueschist facies. 29. Foliated texture is where metamorphic rock is made of layers of materials. 30. This ice flow cut across the Willoughby granodiorite and adjacent metamorphic rocks.
