Study Notes
Exposure to Weathering and Erosion
- Uplift of the Earth's surface exposes rock formations to weathering and erosion.
Nuvvuagittuq Greenstone Belt's Transformation
- The Nuvvuagittuq Greenstone Belt experienced its last rock transformation approximately 4.5 billion years ago.
Coverage of the Greenstone Belt
- The metamorphic rock formations of the Greenstone Belt were covered by a thick layer of sedimentary and volcanic rocks for billions of years.
Weathering and Erosion of the Rock Layers
- The rock layers above the Greenstone Belt were slowly weathered and eroded away due to natural processes such as wind, water, and ice.
Current Condition of the Nuvvuagittuq Greenstone Belt
- The Nuvvuagittuq Greenstone Belt is currently exposed at the surface, revealing its ancient rock formations.
Composition of the Nuvvuagittuq Greenstone Belt
- The Nuvvuagittuq Greenstone Belt is composed of some of the oldest and most ancient rocks on Earth, including volcanic and sedimentary rocks that have been transformed by heat and pressure.
