Subduction

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.

Test your knowledge of geological processes with this quiz on subduction and uplift. Learn how the Nuvvuagittuq Greenstone Belt, a formation of metamorphic rock, was able to move deep underground and then resurface. Explore the forces that drive these movements and deepen your understanding of Earth's dynamic processes.
