"Unearthing Scandinavia's Ancient Origins: The Discovery of a 3.75 Billion Year Old Earth's Crust Segment"
Researchers studying zircon crystals in river sand and rocks in Finland have discovered a hidden chunk of Earth's crust that originated in Greenland and played a crucial role in the formation of Scandinavia. The crystals, dating back 3.75 billion years, provide insights into the formation and growth of the oldest parts of the continental crust, shedding light on the birth of continents and their influence on Earth's habitability. This discovery may help understand how other landmasses on Earth formed and spread across the planet.
